Answer:
Star of Jude patches.
Explanation:
The 'Star of Jude' patches were small, yellow patches of fabric with a star of David as well as the word "Jude" (Jew in german) that Jewish people had to sew into their clothes in order for them to be identified by the public. This allowed for public shaming and discrimination as Jewish people were branded by the small patch. It was a law heavily enforced, even wedding dresses and formal clothes not permitted from it.
Sowing division among Panem's people—divvying up the country into twelve districts—and ensuring their dependence upon the government.
This geographic polarization makes the population politically speaking to be very divided because these points of geographical difference are very significant for determining political polarization.
Classical Political Geography has as its precursor the German geographer Friedrich Ratzel, who laid the scientific and systematizing bases for this science with the publication, in 1897, of the work Political Geography. For Ratzel, the strength of the State was closely linked to space - in its shape, extent, relief, climate and availability of natural resources -, to its position - social relations established between the State and its circulating environment at the national and international level - and, finally, to the sense (or spirit) of the people, which represented the strength of that determined people in relation to another. These ideas, understood in a simplistic and distorted way, would be known as "geographic determinism". (Geographical determinism, however, occurs when natural elements are given the sole role in defining the constitutive aspects of societies.)
