At the age of $42,$ Mahavira Swami attained "Kaivalya Gyan".
Mahavira Swami made many sadhus, sadhvis, shravakas and shravikas his followers through his teachings.
According to the beliefs of Jainism, Jainism was established from time immemorial.
The $23rd$ Tirthankar Pashrvanath preached Jainism to the people around $700\ BC.$
Thus, Mahavira Swami is considered a follower of Pashrvanath.
Mahavira Swami gave his sermon in Lokbhasha Ardhamagadhi so that even the common people could easily understand.
Yeast people instinctively accepted Jainism.
About $200$ years after the Nirvana of Mahavira Swami, the followers of the Jain tradition accelerated the spread of Jainism.
In ancient times Jainism was very prevalent in Kalinga.
The Chinese pilgrim Yuan-shawang Kaling is said to have originated in Jainism.
Jainism was spread in Bihar under the auspices of Nandvansh.
Chandragupta Maurya and Emperor Sankrati converted to Jainism.
Ganadhar Bhadrabahu went to South India with his followers during the famine in Magadha at the end of the reign of Chandragupta Maurya.
The followers in Magadha, under the leadership of Ganadhar Sthulibhadra, convened the first "Jain Sabha" in Pataliputra, the capital of Magadha, to compile the teachings of Mahavira Swami and to reconstruct the Jain texts.
There were two sects of Jainism when the followers who had gone to South India returned to Magadha and disagreed on some doctrinal issues on both sides. $(1)$ Shwetambar Sampradaya and $(2)$ Digambar Sampradaya.
"Shwetambar" means the followers of the white-clad monks.
These Jains were proponents of idolatry.
"Digambar" means the followers of the monks who wear directional clothes. Jain monks who believed that Jain monks should not wear clothes were called "Digambar".
Although two sects emerged in Jainism, Jainism spread widely in India.
The inscription on the $2nd$ century $BC$ "Elephant Cave" of Kharvel, the king of the Chaulvans, from Udayagiri near Cuttack, shows that these holidays converted to Jainism.
An inscription found in Mathura in the early century AD shows that Mathura has long been a major center of Jainism.
Holidays of the Ganga, Kadamba, Chalukya and Rashtrakuta dynasties at Shravanabelagoda in Mysore, South India, allowed the propagation of Jainism in their state.
As a result, Jainism spread well in these states as well.
Thus, Jainism was propagated and spread in Maharashtra, Rajasthan, Gujarat and other states of India.
