Final answer:
Douglass' meetings with President Lincoln contributed to the national conversation on civil rights, and the Emancipation Proclamation issued by Lincoln led to the abolition of slavery in Confederate states.
Step-by-step explanation:
During Douglass' meetings with President Lincoln, they discussed strategies for achieving racial equality and the importance of ending slavery, which contributed to the broader national conversation on civil rights. However, it was not solely due to their meetings that civil rights expanded. The Emancipation Proclamation, issued by Lincoln, led to the abolition of slavery in Confederate states, which was a significant step in expanding civil rights for African Americans.
