  1. 3/5 Compromise -

    The 3/5 Compromise counted each enslaved person as three-fifths of a free person for both taxation and representation, balancing power between North and South. Mnemonic tip: "3 of 5 stay alive" helps you recall the fraction used. According to the National Archives, this agreement was key in shaping early congressional representation.

  2. Industrial Revolution Innovations -

    The Industrial Revolution brought inventions like the cotton gin, steam engine, and telegraph, transforming America from farms to factories. Remember "CST" (Cotton gin, Steam, Telegraph) to track major breakthroughs. Britannica highlights how these technologies boosted productivity and urban growth.

  3. Sectional Economic Differences -

    The North's economy was industrial and commerce-driven, while the South relied on plantation agriculture and enslaved labor. Use the phrase "Industry up North, Fields down South" to lock in the contrast. University of Virginia research notes these economic divides fueled rising tensions before the Civil War.

  4. Missouri Compromise (1820) -

    This deal admitted Missouri as a slave state and Maine as a free state, drawing the 36°30′ line across the Louisiana Purchase to limit slavery's spread. A quick memory aid is "36 and free" for the latitude line and free states above it. Britannica confirms it was a temporary fix to maintain Senate balance.

  5. Reform Movements: Abolition & Suffrage -

    Abolitionists like Frederick Douglass and suffragists from Seneca Falls championed ending slavery and winning women's voting rights. You can pair "A + S = Rights" to link both movements. The Library of Congress archives show how speeches and petitions drove these social reforms.
