To arrest people who were thought to be radicals

Explanation:

The Palmer raids occurred in 1919 and 1920 during the first Red Scare. They were conducted in order to arrest radical leftists and were usually against Italian and Eastern European immigrants. These were most aggressive against anarchists and communists and resulted in their deportation. This paved the road for later ethnic and racial deportations.

the committees of correspondence were the american colonies’ means for maintaining communication lines in the years before the revolutionary war. in 1764, boston formed the earliest committee of correspondence to encourage opposition to britain’s stiffening of customs enforcement and prohibition of american paper money. the following year, new york formed a similar committee to keep the other colonies notified of its actions in resisting the stamp act. in 1773, the virginia house of burgesses proposed that each colonial legislature appoint a committee for intercolonial correspondence. the exchanges that followed built solidarity during the turbulent times and bring about the formation of the first continental congress in 1774.
