As segregation tightened and racial oppression escalated across the United States, some leaders of the African American community, often called the talented tenth, began to reject Booker T. Washington’s conciliatory approach. W. E. B. Du Bois and other black leaders channeled their activism by founding the Niagara Movement in 1905. Later, they joined white reformers in 1909 to form the National Association for the Advancement of Colored People (NAACP). Early in its fight for equality, the NAACP used the federal courts to challenge disenfranchisement and residential segregation. Job opportunities were the primary focus of the National Urban League, which was established in 1910.
During the Great Migration (1910–1920), African Americans by the thousands poured into industrial cities to find work and later to fill labor shortages created by World War I. Though they continued to face exclusion and discrimination in employment, as well as some segregation in schools and public accommodations, Northern black men faced fewer barriers to voting. As their numbers increased, their vote emerged as a crucial factor in elections. The war and migration bolstered a heightened self-confidence in African Americans that manifested in the New Negro Movement of the 1920s. Evoking the “New Negro,” the NAACP lobbied aggressively for a federal anti-lynching law.
In 1933, President Franklin D. Roosevelt’s New Deal provided more federal support to African Americans than at any time since Reconstruction. Even so, New Deal legislation and policies continued to allow considerable discrimination. During the mid-thirties the NAACP launched a legal campaign against de jure (according to law) segregation, focusing on inequalities in public education. By 1936, the majority of black voters had abandoned their historic allegiance to the Republican Party and joined with labor unions, farmers, progressives, and ethnic minorities in assuring President Roosevelt’s landslide re-election. The election played a significant role in shifting the balance of power in the Democratic Party from its Southern bloc of white conservatives towards this new coalition

Answers to #1:
Raphael Lemkin's definition of genocide was not accepted until after the Holocaust.
Raphael Lemkin had been studying the problem of mass killings of a people group since the 1920s, in regard to Turkish slaughter of Armenians in 1915. He coined the term "genocide" in 1944, in reference then also to the Holocaust. The term uses Greek language roots and means "killing of a race" of people. Lemkin served as an advisor to Justice Robert Jackson, the lead prosecutor at the Nuremberg trials. "Crimes against humanity" was the charge used at the Nuremberg trials, since no international legal definition of "genocide" had yet been accepted. Ultimately, Lemkin was able to persuade the United Nations to accept the definition of genocide and codify it into international law. In December, 1948, the United Nations adopted the Convention on the Prevention and Punishment of the Crime of Genocide, which made use of a number of Lemkin's ideas on the subject.
#2: For item #2, you didn't ask a question, so I won't attempt to guess at what question you might have in mind. The definition as you quote it comes from Article II of the UN's Genocide Convention. Article III also indicts intention and conspiracy to commit genocide as crimes against international law. Article IV of that same Convention then puts teeth into the UN's action, saying, "Persons committing genocide or any of the other acts enumerated in article III shall be punished, whether they are constitutionally responsible rulers, public officials or private individuals."
