The 1920-1923 period of BMM is essentially a non-party assembly. Anatolia and Rumelia Defence of Rights Association was established in Sivas Congress, but forming political parties was decided to be discussed later after the National Struggle. Immediately after the opening of the Assembly there were small groups operating within the Assembly. The most well-known of these are ‘Tesanut Group’, ‘Istiklal Group’, ‘Müdafaa-i Hukuk Group’, ‘Halk Group’ and ‘Islahat Group’. Deputies who did not take part in this group or did not want to participate in the Assembly first carried out an unorganized activity in the Assembly, and later in July 1922, they established the Second Defence of Rights Association (Second Group). The deputies who did not participate in both groups received the name of the Independent Group as a third group. According to the figures given by Frey, the First Group consisted of 197 members, the Second Group consisted of 118 members and the Independent Group consisted of 122 deputies (Frey, 1965, p. 307). It should be noted that the struggle between these three groups mainly occurred within the Assembly and their reflections to the public was weak.
