I want to know the answer to the following question:
How early did the small republic states exist in India?
All the background I'm provided with is that "Early "republics" such as the Vajji (or Vriji) confederation centered in the city of Vaishali, existed as early as the 6th century BCE and persisted in some areas until the 4th century CE.". Is that enough to answer the question?
Answer: yes
