Answer:
Constitutional Convention and Ratification, 1787–1789
The Constitutional Convention in Philadelphia met between May and September of 1787 to address the problems of the weak central government that existed under the Articles of Confederation. The United States Constitution that emerged from the convention established a federal government with more specific powers, including those related to conducting relations with foreign governments. Under the reformed federal system, many of the responsibilities for foreign affairs fell under the authority of an executive branch, although important powers, such as treaty ratification, remained the responsibility of the legislative branch. After the necessary number of state ratifications, the Constitution came into effect in 1789 and has served as the basis of the United States Government ever since.

During the late 1800s in Poland and Russia, anti-Semitism took the form of violent attacks called Pogrom.
These attacks forced many Jews to flee to western Europe. Nonetheless, some Jews continued to survive in eastern Europe in small villages called Shtetlekh.
Pogrom is a Russian word which means to wreak havoc or to demolish violently. Historically, the term refers to violent attacks by local non-Jewish populations on Jews in the Russian Empire and in other countries.
Shtetlekh were small towns with large Jewish populations, which existed in Central and Eastern Europe before the Holocaust.
