The TANU served a vital purpose in aiding the localized Ujamaa villages. TANU supplied larger resources such as access to clean water, construction material, and funding for supplies. Furthermore, TANU aided local communities by creating elections and forms of representation for the larger political party. Furthermore, TANU persuaded individuals throughout Tanzania to join the communal living within the Ujamaa Villages. This allowed for Ujamaa villages to thrive as professionals would leave their professions in other cities to join the Ujamaa movement. This created the legitimacy and social traction that the Ujamaa program needed to make a mark on the international community.
