This document is a student's history timeline project on the theme of diversity and inclusion in American history. It discusses how immigration, nativism, and citizenship laws have both allowed and prevented people's inclusion at different points. The timeline then outlines five pre-emancipation events: 1) The beginning of slavery in 1619, 2) The Declaration of Independence, 3) The Trail of Tears, 4) King Cotton establishing the South's economic reliance on slavery, and 5) Lincoln's Emancipation Proclamation freeing slaves in rebel states. The student chose this theme because understanding who was and was not included is important to comprehending US history fully.
