If you search the topic boycotts on Google you immediately realize how historically common they are. There are a lot to choose from, and one of the first listed is the 1769 boycott instituted by the First Continental Congress against Great Britain over the issue of “taxation without representation.” That makes a boycott against a perceived oppressive power an integral part of American heritage.
As you move into the modern era, a reaction against racism also becomes a noticeable motivating factor for many boycotts. The Chinese instituted a boycott against the United States over the Chinese Exclusion Act of 1892 and 1904. Then, in 1933, the American Jewish Congress declared a boycott of Nazi Germany in protest to its racially motivated oppression of the German Jewish community. In the 1940s, Ghandi would encourage Indians to boycott imperial Britain. In the 1950s and 1960s, African Americans would boycott segregated institutions in the U.S. South. In the 1960s through the 1990s, much of the world would boycott South Africa over issue of apartheid. And this is but a short list.
In 2005, 170 Palestinian civil society organizations, including unions, refugee networks, women’s organizations, and political parties, put out a call for a boycott of Israel. This was to be a non-violent effort to pressure the Zionist state to conform to international law and cease its oppression of the Palestinians. The call was also for divestment from Israel and all entities that assisted and profited from its behavior, as well as for eventual sanctions. This is known as the Boycott, Divestment and Sanctions campaign, or BDS for short.

Today, Israel and many US lawmakers trying to support an Apartheid state, are making it ILLEGAL to boycott Israel.
