Yes, Christianity was spread by mostly Europeans worldwide too.
Read about the Church of the East -- the Assyrian church (a.k.a. the Holy Church of the East) - in the 8th century this had more people and a wider population than the church in Europe.
The missionaries converted people and preached and pastored to people in Yemen, Syria, Iraq, Iran, India, all the way to Mongolia and western China.
What happened to this? Islam -- Timur-e-Lang, the greatest jihadi warrior killed most -- he was a master of genocide, having killed 5% of the world's population (more than GEnghis khan, Stalin, Mao etc.)
The largest Christian group today is the Syriac Church
And the word of God today is by Christians of different ethnic backgrounds.
If the English, French and Dutch had even a fraction of the zeal of the Iberians, then much of the world would be Christian
Instead the Dutch did nothing, nothing to convert people -- preferring to just grab the wealth of Indonesia.
The French and English were slightly better in proselytisation, but still woefully behind the IBerians.
oh and the Russians also spread Christians into Siberia and Alaska
