Juq great revelation!!!! UK, Germany and France are 3 different countries!!! Nah seriously, I wrote those 3 because they had almost the same GPD and were depending on the years after 1950 behind or above the ranking list.
Also I am kinda surprised to not see China in the top of the list before the 1700s, as many scholars and economists proved that China was continuously the first world power since old times.
I decided to put Italy (despite the fact that it was not an unified nation) above Spain/Portugal in the 1500s (Spain and Portugal unified themselves for a short period but later in the 1600s), Italy was clearly the most developped western european nation during the renaissance.
After 2100 do not take it seriously just pure fantasy :)

Spain was clearly out after the 1600s, soon after the Spanish Armada was defeated and the Habsburg dominion dismantled, facing a crisis and slowly losing ground in America (Caribbean, North America etc.)
1500s: Ottoman Empire, Spain, Portugal 1600s: Spain, France, Ottoman Empire, 1700s: France, United Kingdom, Qing Empire 1800s: United Kingdom, Russia, France 1900-1950: United Kingdom, Germany, United States, Russia 1950-2000: United States, Russia, China, United Kingdom Nowadays: United States, China, Russia
Germany was powerful at the beginning...but then the Versailles Treaty (1919)...very poorness 1919-1936, then great victories, then back to very poorness (1945-1980s around).
1500s: Spain, Portugal, Ottoman Empire 1600s: Spain, Portugal, Ottoman Empire 1700s: Spain, Portugal, Russia 1800s: Russia, Britain, France 1900-1950: Britain, France, Russia 1950-2000: Russia, America, Japan Nowadays: China, America (EU also if they are taken into account together)
Juq Spain in the 1700s was no longer a powerful nation nor Russia still barely in the middle age during that period. And again China was number one at least until 1600-1700.
