How to thank civil right African American Activist for their work?

To be honest I don't think this is worth stressing over you get to meet a great person who did a lot to make this future I think the best thing you could do is stay respectful and just say it if you feel the need to. Thank you so much. It doesn't hurt if you do your research on that specific person if you want to ask about specific events they were involved in

The inca empire met the same fate as the aztec empire. smallpox would also another spanish conquistador, francisco pizarro; conquer the incas in south america. pizarro was able to capture the inca ruler, atahualpa, easily. pizarro promised that he would release atahualpa if the inca's gave him gold.
