Aztec
From Tardis Wiki, the free Doctor Who reference
The Aztec were a Human ethnic group native to Mexico. Some of their acheivements were creating a calendar and the cronsuction of massive pyramid-like tombs and temples. A very religous people, they beleived in gods which needed constant human sacrifice to be appeased and built many temples. They were also extremely warlike.
Apparently, it was a custom for a male to present a cup of coffee a female whom he wanted to marry.
The Doctor and his companions encountered Aztecs in the 15th century. (DW: The Aztecs)
