Bosnia and Herzegovina
Religious segregation has been practiced in Bosnia and Herzegovina since the 12th century. Being historically a multi-ethnic and multi-religious nation, ethnicity and religion are interchangeable within the nation: Croatians are largely Catholic, Bosniaks are largely Muslim, and Serbs are largely Orthodox. These ethnoreligious linkages have influenced political and cultural dynamics, especially during periods of political dominance under foreign dominance where in one group would hold power over the others. Bosniak Muslims held more political influence and power under the Ottoman Empire than any other group, the Catholic Croats held power under the Austro-Hungarian Empire, and the Serbs held major political influence during the Kingdom of Yugoslavia.
Schooling in Bosnia and Herzegovina has been segregated by religion with educational services being provided by religious groups and organizations, this practice finds its roots as far back as the Vidovdan Constitution of 1921. Religious segregation in schooling continued during Communist Yugoslavia with government intervention proving ineffective. Since 1995 with the implementation of the Dayton Agreement, the Bosnian government has agreed and maintained upon a “two schools under one roof policy”, allowing religious schooling to continue as a form of cultural protection. In 2014, Herzegovina-Neretva became the first canton to ban religious schooling.

The debate over the ban on non-Hindus entering Hindu temples began around 30 years ago when singer Yesudas, who planned to take part in a music program, was stopped at the Guruvayur Temple gate. He finally had to sing bhajans outside the temple wall. Though several temples in Kerala have signs saying non-Hindus are barred entry, few of them enforce it as strictly as Guruvayur Temple, which insists on following its distinct traditions. 'Only Orthodox Hindus are allowed’, reads a signboard hanging from the Lion's Gate of the Sri Jagannath Temple in Puri. The issue has triggered many a controversy in the past and continues to arouse strong feelings even today.
In the past a number of dignitaries, including former prime minister Indira Gandhi, had not been allowed to enter the 12th century shrine; she was married to a Parsi, Feroze Gandhi. In 2005, Princess Mahachakri Sirindhorn of Thailand was not allowed inside the temple as she is a Buddhist.]]
The partition of India entailed creating two countries - India and Pakistan - on the basis of religion, as demanded by Muhammad Ali Jinnah and the All India Muslim League, though not without significant opposition.
In the colonial Indian province of Sind, the historian Ayesha Jalal describes the actions that the All India Muslim League used in order to undermine the government of Allah Bakhsh Soomro, which stood for a united India:
