Tulu Nadu in the context of "Architecture of Kerala"

The Deccanis or Deccani people are an Indo-Aryan ethno-religious community of Urdu-speaking Muslims who inhabit or are from the Deccan region of India. The community traces its origins to the shifting of the Delhi Sultanate's capital from Delhi to Daulatabad in 1327 during the reign of Muhammad bin Tughluq. Further ancestry can also be traced from immigrant Muslims referred to as Afaqis, also known as Pardesis who came from Central Asia, Iraq, and Iran and had settled in the Deccan region during the Bahmani Kingdom (1347). The migration of Muslim Hindavi-speaking people to the Deccan and intermarriage with the local Muslim converts from Hinduism, led to the creation of a new community of Hindustani-speaking Muslims, known as the Deccani, who would come to play an important role in the politics of the Deccan. Their language, Deccani, emerged as a language of linguistic prestige and culture during the Bahmani Sultanate, further evolving in the Deccan sultanates.

Following the demise of the Bahmanis, the Deccan sultanate period marked a golden age for Deccani culture, notably in the arts, language, and architecture. The Deccani people form significant minorities in the Deccan, including the Maharashtran regions of Marathwada and Vidarbha, and the states of Telangana, Andhra Pradesh, Karnataka (except Tulu Nadu), and northern Tamil Nadu. They form a majority in the old cities of Hyderabad and Aurangabad. After the partition of India and the annexation of Hyderabad, large diaspora communities formed outside the Deccan, especially in Pakistan, where they make up a significant portion of the Urdu speaking minority, the Muhajirs.

The Tulu language (Tuḷu Bāse, Tigalari script: 𑎡𑎻𑎳𑎻 𑎨𑎸𑎱𑏂, Kannada script: ತುಳು ಬಾಸೆ, Malayalam script: ത‍ുള‍ു ബാസെ; pronunciation in Tulu: [t̪uɭu baːsɛ]) is a Dravidian language whose speakers are concentrated in Dakshina Kannada and in the southern part of Udupi of Karnataka in south-western India and also in the northern parts of the Kasaragod district of Kerala. The native speakers of Tulu are referred to as Tuluva or Tulu people and the geographical area is unofficially called Tulu Nadu.

The Indian census of 2011 reported a total of 1,846,427 native Tulu speakers in India while the 2001 census had reported a total of 1,722,768 native speakers. There is some difficulty in counting Tulu speakers who have migrated from their native region as they are often counted as Kannada speakers in Indian census reports.

Tigalari is a Southern Brahmic script which was used to write Tulu, Kannada, and Sanskrit languages. It was primarily used for writing Vedic texts in Sanskrit. It evolved from the Grantha script.

The oldest record of the usage of this script found in a stone inscription at the Sri Veeranarayana temple in Kulashekara here is in complete Tigalari script and Tulu language and belongs to the 1159 CE. The various inscriptions of Tulu from the 15th century are in the Tigalari script. Two Tulu epics named Sri Bhagavato and Kaveri from the 17th century were also written in the same script. It was also used by Tulu-speaking Brahmins like Shivalli Brahmins and Kannada speaking Havyaka Brahmins and Kota Brahmins to write Vedic mantras and other Sanskrit religious texts. However, there has been a renewed interest among Tulu speakers to revive the script as it was formerly used in the Tulu-speaking region. The Karnataka Tulu Sahitya Academy, a cultural wing of the Government of Karnataka, has introduced Tuḷu language (written in Kannada script) and Tigalari script in schools across the Mangalore and Udupi districts. The academy provides instructional manuals to learn this script and conducts workshops to teach it.

Malayalam script (Malayāḷa lipi; IPA: [mələjaːɭə lipi] / Malayalam: മലയാളലിപി) is a Brahmic script used to write Malayalam, the principal language of Kerala, India, spoken by 45 million people. It is a Dravidian language spoken in the Indian state of Kerala and the union territories of Lakshadweep and Puducherry (Mahé district) by the Malayali people. It is one of the official scripts of the Indian Republic.

The Malayalam script resembles Tulu script and Tigalari script, used to write the Tulu language, spoken in coastal Karnataka (Dakshina Kannada and Udupi districts) and the northernmost Kasargod district of Kerala. Like many Indic scripts, it is an alphasyllabary (abugida), a writing system that is partially "alphabetic" and partially syllable-based. The modern Malayalam alphabet has 15 vowel letters, 42 consonant letters, and a few other symbols. The Malayalam script is a Vatteluttu alphabet extended with symbols from the Grantha alphabet to represent Indo-Aryan loanwords.The script is also used to write several minority languages such as Paniya, Betta Kurumba, and Ravula. The Malayalam language itself has been historically written in several different scripts.

The Tulu people or Tuluvas are an ethno-linguistic and ethno-cultural group from Southern India. They are native speakers of the Tulu language and the region they traditionally inhabit is known as Tulu Nadu. This region comprises the districts of Dakshina Kannada, Mangalore, and Udupi in Karnataka, part of Kasaragod district in Kerala, with Mangalore, Karnataka being the commercial hub. The Census report of 2011 reported a population of 1,846,427 native Tulu speakers living in India.
