Because all citizens, whether patrician or plebeian, received the same vote in the comitia tributa, and because the assembly was much simpler to convene than the comitia centuriata, the comitia tributa was Rome's most democratic assembly. By the end of the Republic, the plebs greatly outnumbered the patricians, and it was through this comitia that the collective will of the citizens could be exercised without regard to wealth or status.
The comitia tributa, where all citizens had equal voting rights regardless of social class, was Rome's most democratic assembly. This assembly was simpler to convene than the comitia centuriata and allowed for the expression of the collective will of the people without regard to wealth or status.
