Jackson--his presidency was marked by the Indian Removal Act and forced migration of the Cherokee people.
Jackson supported the right of white men to land access in the Southeast. Though the Cherokee had assimilated, owned land, and had created a democratic government they were still not white and therefore not fully accepted by the American people or society. Jackson supported Georgia's efforts to relocate the Cherokee which led to the Trail of Tears and relocation to Indian Territory now the state of Oklahoma.
During the Five Year Plans Stalin created an almost pure command economy. If he needed food, he requisitioned it. If that didn't work, he had the country-side searched for private stocks which he confiscated, having first killed its owners. If he wanted to build a factory in the Urals, he sent people there to build it using food and materials he had requisitioned elsewhere. He killed maybe 15 million people he thought were opposing his policies. He also inspired workers very effectively, convincing them that they were building a new type of civilization, and were in fact becoming a new and better type of human being. He was helped in this endeavor by the fact that the entire rest of the world was manifestly against the Soviet experiment and wanted it to fail. The workers believed their lives depended on rapid industrialization, and given the rise of fascism, and their leaders murderous resolve, they were right.
