How did slavery change over time? What were some of the causes of these changes?

The 13th Amendment, adopted on December 18, 1865, officially abolished slavery, but freed Black peoples’ status in the post-war South remained precarious, and significant challenges awaited during the Reconstruction period.

Previously enslaved men and women received the rights of citizenship and the “equal protection” of the Constitution in the 14th Amendment and the right to vote in the 15th Amendment, but these provisions of Constitution were often ignored or violated, and it was difficult for Black citizens to gain a foothold in the post-war economy thanks to restrictive Black codes and regressive contractual arrangements such as sharecropping.

Despite seeing an unprecedented degree of Black participation in American political life, Reconstruction was ultimately frustrating for African Americans, and the rebirth of white supremacy—including the rise of racist organizations such as the Ku Klux Klan (KKK)—had triumphed in the South by 1877.

Almost a century later, resistance to the lingering racism and discrimination in America that began during the slavery era would lead to the civil rights movement of the 1960s, which would achieve the greatest political and social gains for Black Americans since Reconstruction.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
