The constituency was created for the
1920 election, following the redrawing of districts in the Hanover/Hamburg region. Under the
proportional representation electoral system of the Weimar Republic, voters cast a vote for
party lists. Parties were awarded a seat for every 60,000 votes in a constituency. Excess votes were aggregated at two higher levels of seat distribution: an intermediate level combining multiple constituencies, where extra seats were awarded to parties' constituency lists, and a national level where seats were awarded to national lists of each party or alliance. ==Results (1919–1933)==
