Visualizing empires decline

Avé Portugal. Avé!

Many things may be missing but it is mentioned that it is about "... the evolution of the top 4 maritime empires of the XIX and XX centuries by extent." And so, that's correct.

The spanish empire is clearly in decline...

Larga vida al Imperio colonial español!

I quote: "evolution of the top 4 maritime empires"

2:38, byebye French colonial empire :P

Germany, Russia, USA, Ottoman Empire, Austria-Hungary, Qing Empire, Japanese Empire among others are not here...

em 1922 a irlanda tornou-se independente (república da irlanda) e, se não estou em erro não foi aí referido. achei que isso seria importante visto que eles foram a primeira colónia britânica.

i didnt like it for several reasons
first
it doesnt show the HUGE inner european events happing between 1800-1945 that heavily changed balances between the countries
second
where are the big wars? its almost as they didnt suffer at all during those times...
third
without the us and germany this doesnt make any sense - both countries influence history at least as much as gb and france

well but its a good start liked it

Weak
Why just began in 19th century and were the american, ottoman and russian empires among others?

Not mention the historical errors, Cuba for example became formally independent at end of 1890's not as appear on video
