Well, I can't write your half page essay for you, but let me give you some talking points to get organized around.
Discrimination against the Jews began almost as soon as Hitler came to power in 1933.
1) Jews were encouraged to leave the country, and thousands did.
2) Starting in 1935 the Race and Resettlement Laws were passed that kicked Jews out of public schools, certain professions like teaching and medicine, and forbid Jews and non-Jews to get married, date or have sexual relations.
3) In 1938 an assassination of a lowly German official by a Jew sparked government sponsored riots across Germany that killed dozens of Jews and led to the arrests of 2000 more. After this Kristallnacht, or "Night of the Broken Glass", discrimination against Jews accelerated.
4) They were segregated into ghettos, starved, forced into labor
5) Jews were deported to concentration camps, where most of them were murdered.
