How did the republic structure of government change and develop overtime

After defeating the Etruscan king, Romans developed a republican government with the intent of limiting one person's claim to power. During its early development, the senate, made up of 300patricians (upper class), controlled the government. In a time of war, the senate picked a dictator to rule for six months.
