Not including wars where industrialized nations slaughtered various brown folk
In North and South America Europeans are successful primarily b/c of disease and secondly continuous ?reinforcement? from Europe. 90% casualties before combat makes it difficult to win.
In most of Africa Europeans are held at bay, in this case often quite literally, by malaria until the discovery/invention of quinine in the early 1850s.
In Asia, European dominance was established using seaborn artillery to bombard coastal and river cities. There were very very few times when Europeans had a land army in Asia that could not be easily over run by the Chinese, Japanese, or Koreans.
