The Pudgalavādins were also known as Vatsiputrīyas after their putative founder. Later this group became known as the Sammitīya school after one of its subdivisions. It died out around the 9th or 10th century CE. Nevertheless, during most of the early medieval period, the Sammitīya school was numerically the largest Buddhist group in India, with more followers than all the other schools combined. The Sarvāstivādin school was most prominent in the north-west of India and provided some of the doctrines that would later be adopted by the Mahāyāna. Another group linked to Sarvāstivāda was the Sautrāntika school, which only recognized the authority of the sutras and rejected the abhidharma transmitted and taught by the Vaibhāṣika wing of Sarvāstivāda. Based on textual considerations, it has been suggested that the Sautrāntikas were actually adherents of Mūlasarvāstivāda. The relation between Sarvāstivāda and the Mūlasarvāstivāda, however, is unclear.
