Final answer:
The Freedmen's Bureau was instrumental in improving literacy among formerly enslaved individuals by establishing schools and higher educational institutions, aiding in the transition to freer, more autonomous lives.
Step-by-step explanation:
The Freedmen's Bureau, formally known as the Bureau of Refugees, Freedmen, and Abandoned Lands, was established in 1865 to assist former slaves during the transition from slavery to freedom. One success of the Freedmen's Bureau in improving life for formerly enslaved people was that it helped raise literacy rates among formerly enslaved people. Through its initiatives to establish schools, the Bureau contributed to the foundation of numerous educational institutions, including Fisk University, Hampton University, and Dillard University. These schools were crucial in teaching reading, writing, and other skills necessary for citizenship and self-advancement.
