In this video Heimler takes you through Unit 7 Topic 12 of the AP U.S. History curriculum which is set in period 7 (1898-1945).

After the United States entered World War II, mobilization began quick, fast, and in a hurry. FDR created government agencies that oversaw the transformation of domestic industrial centers into wartime production factories. And all of this had the effect of increasing GDP by 15% and thus pulled America out of the Great Depression.

Black Americans and Mexican Americans served in the war, some with great distinction. The NAACP encouraged black Americans to participate in the Double V Campaign, which meant they were working for victory abroad and victory over entrenched racism at home. As Mexican Americans left for the war, it left a dearth in agricultural workers and so immigration restrictions were lowered for Mexican citizens who could come and help.

Also on the Homefront, Japanese Americans on the west coast were forcibly removed from their homes and relocated into internment camps because they were associated with the hated Japanese enemy


  1. SAved me SO MUCH damn time instead of having to read my textbook, while retaining SO much more info. You're a REAL ONE Heilmler.

  2. Mr. Heimler, what do you mean when you said "many participated in the war effort as a way to put race issues on the 'national agenda'" what does it mean by national agenda? Minute 2:34

  3. Hi Mr. Heimler, I sincerely want to thank you for creating the APUSH review packet, it has been very helpful with understanding the major concepts. The review videos have chefs kiss quality content and learning U.S. history has been a delight. However, it might be too much to ask, but I was wondering if there were to be any plans for adding subtitles to the video? I think that they would be very helpful in regards to retaining more of the information. Thank you for all your hard work and I hope that you are well during these difficult times.

  4. Hey Mr. Heimler!
    Will you be making unit review videos from now on?
    Also, I can't seem to find the Unit 7 topic 1 video on your channel. Is it just me?

    Thank you for all you do!!
