Marius's election as a consul made the most sweeping changes to the Roman army. They were known as the Marian Reforms. Shortly after his election, he increased the numbers of the active army as he was concerned about a Barbarian invasion. Marius relaxed the strict recruitment policies. Until then, a Roman soldier had to provide his own uniform and weapons, own land and be of a certain social class and a Roman citizen. Marius allowed all Roman citizens to join the army irrespective of what social class they were. They also did not have to own land.
In 1830, Jackson ignored a Supreme Court ruling to sign into law the Indian Removal Act, forcing native people to lands in the West, away from their homes east of the Mississippi river.
The reason: Gold.
Gold had been found on Cherokee land, and Jackson wanted it. The president’s excuse for removal – claiming the Cherokees had violated the constitution by declaring their own state without approval – was a smokescreen.
The native Americans were eventually forced to march 800 miles west. From the 47,000 southeastern Indians that were uprooted, it is estimated that 1 in 4 died from either exhaustion or starvation on what is now called The Trail of Tears. Jackson acquired more than one hundred million acres of land.
The Indian Removal Act was genocide.
Andrew Jackson should not be on the $20 bill I have many more reason but that’s the biggest.
