Peak GDP Year: 1947 (0.6%)

The peak year of 1947, reflects industrialization under Stalin. That number is largely projected backwards from 1973 data and it is hard to believe that war-ravaged Belarus was actually in good condition.

There is little historical information about Northeastern Europe before the 9th century. I have followed Phersu Atlas in ascribing control vaguely known tribal confederations and kingdoms at times.

I have identified the Kievan Rus state as Russia because that it was its contemporaries called it (in Latin). The breakup of the Kievan Rus was a gradual process and I have followed the Phersu Atlas in its timing.

Here is my summary of who controlled Belarus

Peak Year: 933, 1.8% of world GDP

This part of the world is populous but it remained backward economically until recent decades.

Much of the early history of Bangladesh is obscure. Phersu Atlas shows substantial gaps and often contradicts Geacron. The Wikipedia entries are somewhat useful but there seems to be a lack of primary sources.

Phersu Atlas even contradicts ifself. For example, see this map for 700 CE

which contradicts the city data for Dhaka

The 1 year rule of Gauda looks like an error.

Geacron shows a completely different 700 CE

There are also some spelling discrepancies.

I am following the Wikipedia by using Varendra.

I have redid this using Phersu Atlas. Phersu-Atlas is more thorough than other online sources. https://phersu-atlas.com/

The modern nation of Afghanistan had normally been at the periphery of empires.

Peak Year: 2997 BCE (1.2% of world GDP/population)

Here is how I have allocated its territory over time.

Notes

1. I start Afghan history with the Persian conquest. The Gandhara kingdom does not seem to have extended into Afghanistan. The Kamboja kingdom seems to more of language group and its dates are unclear. The Median conquest is also unclear.
2. I allocated the GDP of Afghanistan based upon the following 4 cities: Balkh, Herat, Kabul/Bagram, Kandahar
3. My primary sources have been the Wikipedia and Geacron.

It was common in European feudalism, to have a various territories to have the same ruler despite being administratively and even geographically separated. I view that it is important to show these as being a single state.

In most cases, I identify this by the primary or home territory of the ruler. For example, the Habsburg (or Hapsburg) Empire is called Austria, which also corresponds to what it was actually called during its time.

Peak: 1300 (7.8%)

France was unaffected by the Mongol conquests. Other parts of Europe grew faster after 1300.

Peak Year: 1991 (8.7%)

Japan was the first Asian nation to industrialize. With its large population it became the world’s second largest economy, until China caught up.

Peak: 2999 BC (8.7%)

Intensive agriculture came later to Mexico than the Old World, so Mexico has the highest numbers at the start of the data.

Peak: 1939 (8.8%)

World War Two sharply reduced the size of the German economy. It recovered in its absolute terms, but growth in the rest of the world reduced its relative importance.
