Answer:
The two statements that are true about the members of the Creek tribe after the civil war are in first place that They focused on rebuilding and reestablishing schools and churches, and in second place They wrote a new constitution to attempt to bring peace and unity to the tribe, because the Creek Civil War (from 1813 to 1814) was a war where due to that the Upper Creeks weren't agree with the acceptation of the American encroachments in their lands, they decided to fight against the U.S militia and the Lower Creeks (who accepted the Americans encroachments), which caused that the Upper Creeks were defeated at Horseshoe Bend, and as a result of that, they had to cede to the U.S more than 20 millions of acres. Whereby, time later in 1836 the Creeks were forced to be removed from their homeland and be relocated in the Indian Territory by the U.S Army, but a few Creek branches resisted, so it generated the Creek War of 1836, and then, when the other Creeks (who didn't resisted) arrived to Indian territory, they had to rebuild and reestablish their homes, buildings, churches and schools, to create a new government in their new capital (in Okmulgee) and also they decided to wrote a new constitution with the purpose to restart and bring peace and unity to all Creeks (the Uppers and the Lowers).
