All of the World’s Borders by Age

Defined borders are a relatively new concept in many parts of the world. In fact, until the latter half of the 20th century, most of the world was still wide open territory with loosely or completely undefined borders.
On the European continent, however, jurisdiction over territory has been a fact of life for thousands of years. In some cases, they’ve left a paper trail. In other cases, there are more concrete remnants. For example, over 3,000 miles (5,000 km) of simple frontier fortifications – known as limes – marked the edges of the Roman Empire at its greatest extent in the 2nd century.
Over time, as territorial jurisdiction changed hands through war, marriage, and other arrangements, the map has been redrawn countless times. The video below demonstrates just how dramatically many of Europe’s dividing lines have shifted (even as recently as the 1990s).
Even today, borders are far from set in stone. Belgium and the Netherlands recently swapped land in order to simplify an overly complex piece of their border along a river. Also, India and Bangladesh worked together to solve a notoriously complicated situation involving enclaves within enclaves.
The Difficulty in Date Stamping Dividing Lines
Creating a map that shows the age of all the world’s borders seems like an impossible feat, but Reddit user, PisseGuri82, was up to the challenge. PisseGuri82, acknowledging the extreme complexity of the undertaking, outlined some caveats to consider:
– The map looks at the date a border was officially set to its current form (excluding minute changes).
– The dates are derived from publicly available border treaties and documents.
– Exact dates are difficult to pin down as ratification, surveying, and physical marking can take place over a number of years.
These issues aside, the final product is a fascinating look at how we’ve divided the world up into nations. Here are some highlights from the map:
In contrast to the patchwork of territories left in the wake of the Holy Roman Empire, the southwest part of Europe has remained remarkably static. The border dividing Spain and Andorra, weaving its way through the rocky Pyrenees mountain range, has remained unchanged since 1278, when a feudal charter solidified Andorra’s geography. The Portugal–Spain border has been in place since 1297.
War and Pieces
Many of the oldest borders in the world were established by treaties following a war. One particularly noteworthy example is the border between Iraq and Turkey, which was established by the Treaty of Zuhab (1639) following the sack of Baghdad by the Ottoman Empire.
The Legacy of the “Scramble for Africa”
It’s remarkable to note that a full third of the world’s borders are less than 100 years old. This is especially apparent in Africa, where many existing borders still resemble those haphazardly set by colonial powers around the turn of the 20th century. The average border on the continent is only 111 years old.
We have been giving away mountains and rivers and lakes to each other, only hindered by the small impediment that we never knew exactly where the mountains and rivers and lakes were.
-Lord Salisbury, British PM in 1890
In 1964, independent African states chose to maintain colonial borders, primarily to prevent widespread conflict over territory. Though colonial divisions were maintained in theory, only about one third of Africa’s 51,000 miles (83,000 km) of land borders are demarcated – an issue that continues to cause headaches today. For example, South Sudan has numerous border conflicts with neighbors; a situation that is complicated by the presence of natural resources.
A recent study pointed out that the likelihood of conflict in Africa is approximately 40% higher in areas where “partitioned ethnicities reside, as compared to homelands of ethnicities that have not been separated by national borders”.
There are seven sovereign states with pie-slice-shaped territorial claims in Antarctica. It’s worth noting that the claims have been recognized only between the countries making claims. There is currently a treaty in place that preserves freedom of scientific investigation and bans military activity on the continent.
Saudi Arabia’s Lines in the Sand
Saudi Arabia’s oldest border section – shared with Kuwait – is a remnant of the Uqair Convention circa 1922, but most of its international borders were established in the latter part of the 20th century. The Yemen–Saudi border was only officially demarcated in the year 2000, and a 1,100 miles (1,800 km) border fence soon followed.
Where will lines Shift next?
Where there is a war and upheaval, border changes often follow. Syria’s descent into chaos and the annexation of Crimea are two situations which could result in new international borders. Breakaway states – an independent Catalan state, for example – are always a possibility as well.
For now, the most likely changes to borders will continue be minor adjustments to fix lawless gaps between nations. These corrections are rarely easy to negotiate, but irregularities, like the one that led to founding of Liberland, can cause even bigger headaches for governments and local officials.
The 44 Closest Stars and How They Compare to our Sun
This graphic visualizes the 44 closest stars, revealing key facts such as distance from Earth, brightness, and whether potential planets are in orbit.
44 Closest Stars and How They Compare to our Sun
Humans have been fascinated by the stars in the night sky since the dawn of time.
We’ve been decoding the mysteries of celestial bodies for many centuries, but it is only in the last 200 years or so that we’ve been able to glean more detailed information on the lights that dot the night sky. Friedrich Bessel’s method of stellar parallax was a breakthrough in accurately measuring the positions of stars, and opened new doors in the effort to map our universe. Today, high-powered telescopes offer even more granular data on our cosmic neighborhood.
The infographic above, from Alan’s Factory Outlet, categorizes the 44 closest stars to Earth, examining the size, luminosity, constellations, systems, and potential planets of each star.
Our Nearest Stellar Neighbors
Our closest neighboring stars are all part of the same solar system: Alpha Centauri. This triple star system – consisting of Proxima Centauri, Alpha Centauri A, and Alpha Centauri B – attracts a lot of interest because it hosts planets, including one that may be similar to Earth.
The planet, Proxima Centauri b, is a lot closer to its star than Earth is to the Sun. However, because Proxima Centauri is a smaller and cooler red dwarf type star, the planet’s orbit is within the habitable zone. It’s thought that Proxima Centauri b receives approximately the same amount of solar energy as Earth does from our Sun.
Here’s a full list of the 44 of the closest stars to Earth:
|Star Name||Distance (light years)||MoE|
|α Centauri A||4.37||±0.0068|
|α Centauri B||4.37||±0.0068|
|Luyten 726-8 A||8.79||±0.012|
|Luyten 726-8 B||8.79||±0.012|
|EZ Aquarii A||11.11||±0.034|
|61 Cygni A||11.40||±0.0012|
|61 Cygni B||11.40||±0.0012|
|Struve 2398 A||11.49||±0.0012|
|Struve 2398 B||11.49||±0.0012|
|Groombridge 34 A||11.62||±0.0008|
|Groombridge 34 B||11.62||±0.0008|
|Kruger 60 A||13.07||±0.0052|
|Kruger 60 B||13.07||±0.0052|
|Wolf 424 A||14.05||±0.26|
|Van Maanen's star||14.07||±0.0023|
Even though we see many of these stars in the night sky, humans aren’t likely to see them in person any time soon. To put these vast distances into perspective, if the Voyager spacecraft were to travel to Proxima Centauri, it would take over 73,000 years to finally arrive.
The Brightest Stars in the Sky
The closest stars aren’t necessarily the ones most visible to us here on Earth. Here are the top 10 stars in terms of visual brightness from Earth:
|Rank||Proper name||Constellation||Visual magnitude (mV)||Distance (light years)|
|4||Rigil Kentaurus & Toliman||Centaurus||−0.27 (0.01 + 1.33)||4.4|
Excluding our Sun, the brightest star visible from Earth is Sirius, or the Dog Star. Sirius, which is about 25 times more luminous than the sun, visually punctuates the constellation Canis Major.
Filling in the Gaps
The next step in learning more about our surroundings in the cosmos will be seeing which of the stars listed above have planets orbiting them. So far, the 44 stars in the infographic have over 40 planets scattered among them, though new discoveries are made all the time.
With each new mission and discovery, we learn a little bit more about our pocket of the universe.
Visualizing the True Size of Land Masses from Largest to Smallest
Maps can distort the size and shape of countries. This visualization puts the true size of land masses together from biggest to smallest.
The True Size of Land Masses from Largest to Smallest
Is Greenland the size of the entire African continent?
But looking at a map based on the Mercator projection, you would think so.
Today’s infographic comes from the design studio Art.Lebedev and shows the true size of the world’s land masses in order from largest to smallest using data from NASA and Google.
Check out the actual shape and size of each land mass without any distortions.
Distorting Reality: Mercator Misconceptions
Maps can deceive your eyes but they are still powerful tools for specific purposes. In 1569, the legendary cartographer, Gerardus Mercator, created a new map based on a cylindrical projection of sections of the Earth. These types of maps were suited for nautical navigation since every line on the sphere is a constant course, or loxodrome.
Despite the map’s nautical utility, the Mercator projection has an unwanted downside. The map type increases the sizes of land masses close to the poles (such as in North America, Europe, or North Asia) as a side effect. As a result, Canada and Russia appear to take up approximately 25% of the Earth’s surface, when in reality these nations only occupy 5%.
“Things are not always what they seem; the first appearance deceives many.” – Phaedrus
This collection of images above represents the world’s land masses in their correct proportions. Measurements are based on Google Maps 2016 and NASA Earth Observatory maps, with calculations based on the WGS84 reference ellipsoid, or more simply, a specific model of the Earth’s shape in two dimensions.
We take for granted Google Maps and satellite imaging. Making these accurate representations is no small task – the designers went through six steps and many different iterations of the graphic.
Countries are arranged by descending size and shown without external or dependent territories. For example, the total area for the contiguous United States shown does not include Hawaii, Alaska, or overseas territories.
Top 10 Largest Land Masses
Although Mercator maps distort the size of land masses in the Northern Hemisphere, many of these countries still cover massive territories.
|United States (contiguous)||7,654,643|
The top 10 land masses by size account for 55% of the Earth’s total land. The remainder is split by the world’s 195 or so other countries.
Top 10 Smallest Land Masses
Here are the 10 tiniest jurisdictions highlighted on the map:
While the Earth’s land surface has been claimed by many authorities, the actual impact of human activity is less than one would think.
Human Impact: Humbled by Nature
Political borders have claimed virtually every piece of land available. Despite this, only 20% of land on the planet has been visibly impacted by human activity, and only 15% of Earth’s land surface is formally under protection.
The remaining 80% of the land hosts natural ecosystems that help to purify air and water, recycle nutrients, enhance soil fertility, pollinate plants, and break down waste products. The value of maintaining these services to the human economy is worth trillions of U.S. dollars each year.
While some nations are not as big as they look on the map, every piece of land counts.
