the Russian peasant pulled their land together periodically and their ____ divided it according to the needs of indivdal famlies

In your question regarding Russian peasants and their land management, the missing term is "mir."

The mir was a communal form of land organization where peasant communities would collectively manage and allocate land among families. Every few years, the land would be redistributed based on the needs of individual families. This system was essential for balancing the agricultural output and ensuring that each family received an equitable share of the land, taking into account various factors like family size and agricultural capability. The mir was not only a means of land distribution but also fostered a sense of community among the peasants, as decisions were made collectively. However, this system could also lead to disputes and inefficiencies, particularly when individual families had differing agricultural needs or preferences. Overall, the mir played a significant role in the social and economic structure of rural Russia until the reforms of the 19th century began to change land ownership and farming practices.
