Since the beginning of the 20th century, groups of people (usually circles of young friends) moved to Palestine/Israel together. The term "gar'in" originally referred to these groups who came from all across the world. Immigrating in a group provided the support necessary for survival. Many of these groups founded their own kibbutzim. The phenomemon of these groups has been ongoing since before Israel was established in 1948.
A variation of the original Gar'in groups still exist today. Whilst it is rare for gar'in to move to Israel together and form a community, the groups provide support for people interested in moving to Israel. They also provide forums for social-networking, information gathering, and encouragement.
