I guess when the New World was discovered all those proclamations and decrees went out the window.
“1435: Papal Encyclical Sicut Dudum of Pope Eugene IV banning enslavement on pain of excommunication.”
Please name for me anyone, in a position to matter, who was excommunicated for slavery between the years 1492-1886. As they say, talk is cheap.
You’re right. Your Catholic ancestors were sure bad Christians.
Cases in point:
Abp. Dolan: American Catholic Leadership against Abortion Redeems Laxity against Slavery
Statue of first Catholic Supreme Court justice may go [Chief Justice Taney/"Dred Scott" decision]
Black History: The Slave Coast
The Jesuits Slaves
My Aunt Lucy was excommunicated in 1493. So there!
You understand what latae sententiae excommunication is, right? That it's automatic and requires no decree or other notice by church authority?
This is worth your time:

Pope Zachary excommunicated Venetian slave traders in 750. Not within your time frame, however.
According to J. Pashington Obeng’s Asante Catholicism: Religious and Cultural Reproduction Among the Akan of Ghana, anyone violating Urban VIII’s letter against slavery in the West Indies and Africa was “automatically excommunicated” (page 112).
Protestants sometimes excommunicated slaves for threatening to flee their enslavement: See Donald G. Matthew, Religion in the Old South (page 147). Nobody’s perfect, right?
