In Buddhas Time Did Kings give Freedom to His Sex Wives(Anttappura Wives)? in lord Buddhas time their was many kingdoms in India. these kingdoms had many kings. kings had many wives. some kings had 500, 1000 (Antappura) wives but they all have main 1 queen &amp; other wives used for sex uses.most of these kings became followers of Buddhism &amp; Buddha &amp; they obtain nirvana (1st 3 stages as below) 


The First Stage – Skt srotaapanna (The stream-winner)
The Second Stage – Sakridagamin
The Third Stage – Anagamin (The non-returner) 

so my question is after these became Buddhist &amp; obtain nirvana did these kings given freedom to these Wives who use for sex uses?
One such instance was King Bimbisara giving freedom to Khema to enter the order. Many more may be found in the cemeteries and many may not even be documented!
