What major historical transition began around Lincoln's death?

• A. Reconstruction
• B. The Progressive Era
• C. The Louisiana Purchase
• D. The Industrial Revolution

Answer: (A)

Reconstruction is the major shift being tested. With the Civil War ending in 1865, the nation faced how to reunite the Union and redefine the status and rights of newly freed African Americans. Reconstruction aimed to readmit Southern states into the Union, rebuild the South’s economy and governments, and secure civil and political rights for freedpeople, including the push toward constitutional amendments. Lincoln’s assassination that year meant his vision for a quicker, more conciliatory rebuilding process influenced the early policy direction, but the period of Reconstruction—roughly 1865 through the late 1870s—became the defining national project that followed his death.

The other options don’t fit the timing or focus. The Progressive Era comes later and centers on reforms in the late 19th and early 20th centuries. The Louisiana Purchase occurred in 1803, long before Lincoln’s time. The Industrial Revolution describes broader, ongoing industrial and economic change that began earlier and is not anchored to Lincoln’s death.
