Malabar Coast in the context of "Discovery of the sea route to India"

Islam is India's second-largest religion, with 14.2% of the country's population, or approximately 172.2 million people, identifying as adherents of Islam in a 2011 census. India has the third-largest number of Muslims in the world. Most of India's Muslims are Sunni, with Shia making up around 15% of the Muslim population.

Islam first spread in southern Indian communities along the Arab coastal trade routes in Gujarat and in Malabar Coast shortly after the religion emerged in the Arabian Peninsula. Later, Islam arrived in the northern inland of Indian subcontinent in the 7th century when the Arabs invaded and conquered Sindh. It arrived in Punjab and North India in the 12th century via the Ghaznavids and Ghurids conquest and has since become a part of India's religious and cultural heritage. The Barwada Mosque in Ghogha, Gujarat built before 623 CE, Cheraman Juma Mosque (629 CE) in Methala, Kerala and Palaiya Jumma Palli (or The Old Jumma Masjid, 628–630 CE) in Kilakarai, Tamil Nadu are three of the first mosques in India which were built by seafaring Arab merchants. According to the legend of Cheraman Perumals, the first Indian mosque was built in 624 CE at Kodungallur in present-day Kerala with the mandate of the last ruler (the Tajudeen Cheraman Perumal) of the Chera dynasty, who converted to Islam during the lifetime of the Islamic prophet Muhammad (c. 570–632). Similarly, Tamil Muslims on the eastern coasts also claim that they converted to Islam in Muhammad's lifetime. The local mosques date to the early 700s.

The Oriental Orthodox Churches are Eastern Christian churches adhering to Miaphysite Christology, with approximately 60 million members worldwide. However, the Oriental Orthodox Churches, individually, claim approximately 87 million baptized members. The Oriental Orthodox Churches adhere to the Nicene Christian tradition. Oriental Orthodoxy is one of the oldest branches in Christianity.

As some of the oldest religious institutions in the world, the Oriental Orthodox Churches have played a prominent role in the history and culture of countries and regions such as Armenia, Egypt, Eritrea, Ethiopia, Sudan, the Levant, Iraq and the Malabar region of southern India. As autocephalous churches, their bishops are equal by virtue of episcopal ordination. Their doctrines recognize only the first three ecumenical councils as valid.

Kerala is a state on the Malabar Coast of India. It was formed on 1 November 1956 under the States Reorganisation Act, which unified the country's Malayalam-speaking regions into a single state. Covering 38,863 km (15,005 sq mi), it is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Laccadive Sea to the west. With 33 million inhabitants according to the 2011 census, Kerala is the 13th-most populous state in India. It is divided into 14 districts, with Thiruvananthapuram as the capital. Malayalam is the most widely spoken language and, along with English, serves as an official language of the state.

Kerala has been a prominent exporter of spices since 3000 BCE. The Chera dynasty, the first major kingdom in the region, rose to prominence through maritime commerce but often faced invasions from the neighbouring Chola and Pandya dynasties. In the 15th century, the spice trade attracted Portuguese traders to Kerala, initiating European colonisation in India.
