Gamaliel Foundation provides training and consultation and develops national strategy for its affiliated congregation-based community organizations. As of 2008, Gamaliel has 60 affiliates in 21 U.S. states, the United Kingdom, and five provinces of South Africa, and claims to represent over a million people.

The Gamaliel Foundation was founded in Chicago in 1968 to assist the Contract Buyers League, which worked to assist African-American home buyers in the city’s West Side. Gamaliel was reoriented to focus on community organizing when Gregory Galluzzo was hired as executive director in 1986. Seeing its basic function as training and developing leaders in low-income communities, Gamaliel’s goal is “to assist local community leaders to create, maintain and expand independent, grassroots, and powerful faith-based community organizations” that have the power to influence political and economic decisions that impact cities and regions. The name “Gamaliel” refers to the Biblical wise man who was a teacher to St. Paul (see Acts 5:38-39; and Acts 22:3), whom Saul Alinsky considered to be the first great congregation-based organizer.

Gamaliel the Elder (English pronunciation: /ɡəˈmeɪljəl/), or Rabban Gamaliel I (רבן גמליאל הזקן; Greek: Γαμαλιήλ ο Πρεσβύτερος), was a leading authority in the Sanhedrin in the mid 1st century CE. He was son of Simeon ben Hillel, and grandson of the great Jewish teacher Hillel the Elder, and died twenty years before the destruction of the Second Temple in Jerusalem (70 CE). He fathered a son, whom he called Simeon, after his father, and a daughter, whose daughter (i.e., Gamaliel's granddaughter) married a priest named Simon ben Nathanael. The name Gamaliel is the Greek form of the Hebrew name meaning reward of God.

In the Christian tradition, Gamaliel is celebrated as a Pharisee doctor of Jewish Law.Acts of the Apostles speaks of Gamaliel as a man of great respect who spoke in favor of arrested Christian apostles and the Jewish Law teacher of Paul the Apostle.

In the Talmud, Gamaliel is described as bearing the titles Nasi and Rabban (our master), as the president of the Great Sanhedrin in Jerusalem; although some dispute this, it is not doubted that he held a senior position in the highest court in Jerusalem. Gamaliel holds a reputation in the Mishnah for being one of the greatest teachers in all the annals of Judaism:

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
