Video: The 5 Largest Cities Throughout the Course of History



The world’s most influential cities have certain attributes that make them appear timeless.

Metropolises like New York City, Hong Kong, Shanghai, and London have unprecedented size, opportunities, economic might, and cultural significance, that it’s easy to imagine them as permanent and unparalleled fixtures on the world stage.

However, any glance at world history shows us immediately that these places are not as exceptional or as timeless as we would like to think. Over time, it seems that even the most important cities eventually fall or slip in status.

That’s why a glance at the record books can be humbling, as we come across the names of many ancient cities that were the most important during their time – places like Luoyang, Ctesiphon, Pataliputra, and Constantinople – that today, the majority of people are much less familiar with.

The 5 Largest Cities Over Time

Today we present to you two videos from the Ollie Bye Youtube channel that show the rapidly changing history of the world’s top cities by population.

It’s incredible to watch the rise and fall of these cities, especially when we’re talking about the centers that were the undisputed heavyweight champions of their day.

The 5 Largest Cities (Years: 3000 BC to 1600 AD)

Over this massive span of time, the designation of the world’s most populous city shifts 16 times.

Rome keeps the title for an impressive period – over 400 years – while Baghdad and Chinese cities also have impressive runs as well. However, what’s most provoking about the video is the list of lesser-known cities that have held the title, such as Chang’an, Merv (Marv), and Pi-Ramesses.

The 5 Largest Cities (Years: 1600 to 2100)

During this much shorter stretch of time of more modern history, the rate of urbanization is skyrocketing and cities are now growing at exponential rates.

The most populous city shifts nine times – and by the year 2100, it’s projected that the five most populous cities could have 370 million people living between them.

This would be higher than the total population of the entire world in the 12th century.

We map out America’s largest landfills, based on their total capacity (measured in millions of tons) for solid waste. Data for this graphic is sourced from Statista and is current up to 2023.

According to the EPA, the U.S. produced 292 million tons of solid waste in 2018. Of that, about 150 million tons headed to the country’s landfills. It would take more than 600 of the largest cargo ships (by dead weight tonnage) to move this much material at once.

Ranked: America’s Largest Landfills

Opened in 1993 and located 25 minutes from Las Vegas, Apex Landfill is believed to be one of the world’s largest landfills by both area and volume.

It spans 1,900 acres, or roughly the size of 1,400 football fields. Given its vast capacity, the landfill is expected to be able to accept waste for over 250 years.

Here are the top 10 largest landfills in the country.

In a 2021 PBS interview, a spokesperson for Apex Landfill reported that the facility captured and treated enough landfill gas to power nearly 11,000 homes in Southern Nevada.

In fact, landfills can create electricity through a process called landfill gas (LFG) recovery. When organic waste decomposes, it produces methane gas which can be captured and purified to create fuel for generators.

As it happens, methane gas from landfills is the third-largest source of human-related carbon emissions, equivalent to 24 million gas passenger vehicles driven for one year. Its capture and treatment is a significant opportunity to combat emissions.
