The reference to Asians being brought to the Colonies and the US escapes me.
How is that? In the 1800s, there were apparently about half a million Indian and a quarter million Chinese slaves taken to the US. The East India Company held around about 1.2 million Indian slaves - that company was also delivering tea to Boston ;)
I'm trying to find accurate counts the Chinese started coming around 1834 with the Emancipation Proclamation in 1863. California's Constitution of 1849 explicitly barred slavery. There's no doubt they weren't treated well but the number of enslaved seems to be low.
Indian (Asian) Slaves appear to have been more common but not as numerous as African slaves in Colonial America, digging into it looks more confined to the pre-Revolutionary period.
