Which of the following developments transformed the lives of millions of African Americans in the period immediately prior to the First World War through the end of the Great Depression?

The western states were pioneers in women's suffrage, with Wyoming being the first state to grant women the right to vote in 1869. This trend continued in other western states, leading to a significant number of women enjoying voting rights before the Nineteenth Amendment was ratified in 1920. This early adoption of suffrage contributed to the perception of the West as more progressive regarding gender equality.

The southeastern states generally maintained more traditional views on gender roles and were slower to adopt women's suffrage. Many of these states implemented laws that restricted voting rights for women, reflecting the region's conservative social norms and resistance to change regarding gender equality.

While New England and New York had some progressive movements, they did not grant women the right to vote as early as the western states. Women in these regions faced significant barriers to voting rights, and it wasn't until the national movement gained momentum that suffrage was achieved through the Nineteenth Amendment.

The Deep South and Texas were among the last regions to consider women's voting rights, adhering to traditional patriarchal values. These areas largely resisted the suffrage movement until the national amendment mandated change, creating significant delays in recognizing women's voting rights.
