There are 700-odd districts in India (and I don't know much about most of them). Thread to read about one district each day via . Starting with...
1. (A&N) Nicobar:

Spans the entire Nicobar Islands. Came into being in 1974. HQ: Car Nicobar.

What's the etymology of Car, I wonder. There's a language called Car.
2. (A&N) North and Middle Andaman, HQ: Mayabunder

Interesting ecosystem: turtle nesting grounds and more.

Intriguing: Interview Island-home to elephants that once were used for the timber trade

You can hear Tamil, Bangla in those parts!
I move from A&N in a north-westerly direction, to Andhra Pradesh. Post its bifurcation, AP now has 13 districts. But each has been very influential in different ways in the political/geographical/historical canvas of India. The first district, in alphabetical order is...
4. (AP) Anantapur, HQ: Anantapur
Formed in 1882 and borders Karnataka. Intensely political, a hotbed of 'factionalism' (look up its history). Puttaparthi is in this district. Boasts of a tennis academy associated with Rafa Nadal!
(minor note for thread followers: I had to reconstitute this thread to ensure tweets were properly sequenced in one thread.)
5. (AP) Chittoor. HQ: Chittoor
Religion, business, and history - all in this district, which given its geography, has connections to both Telugu-land and Tamil-land.

Rumour has it the Kohinoor was mined here.
(7 contd.) ....And don't miss its connection to the discovery of Helium. A spectral analysis of the Sun's chromosphere during an 1868 solar eclipse observed from here directly led to element #2 (which was then named after the Sun).

8. (AP) Krishna. HQ: Machilipatnam
Named after the great Krishna river, this coastal dist. is central to Telugu culture. Vijayawada is the big city here. Home to Kondapalli toys and the village of Kuchipudi, where the eponymous dance form originated

(12 contd.) ...was added to the district's name.

14. (AP) Vizianagaram HQ: Vizianagaram

(16 contd.)
In 2010, the district's name was modified to add the initials of Y S Rajasekhara Reddy, the then recently deceased AP CM, who was born here.
And that brings me to the end of my AP sojourn. I realised that I haven't been to any of these districts (and hence the state, post-bifurcation), except in transit.

Next, I will head to Arunachal Pradesh, another state I haven't been to. Did you know it has 25 districts?
17. (AR) Anjaw. HQ: Hawai
Welcome to Arunachal Pradesh. We start with the easternmost district in mainland India, also the 2nd least populated Indian district. There's a trijunction of India, China, and Myanmar here - so strategically super-important. Created in 2004.
18. (AR) Changlang. HQ: Changlang
Changlang is just below Anjaw. The name refers to a hill where a poisonous herb used for fishing was found.
Saw action during WWII, with the Stilwell Road passing through it. Tribal, picturesque, lots of wildlife.
19. (AR) Dibang Valley. HQ: Anini

20. (AR) East Kameng. HQ: Seppa
A western district in the state, and named for the Kameng river (a recurring template for district names in this state). Almost entirely mountainous, and tribal. Borders Assam.
21. (AR) East Siang. HQ: Pasighat
The Bramhaputra is called Siang in this region. 5 districts bear its name, a sign of its significance. The mountainous East Siang is home to Pasighat, the oldest British town in this area, and the Daying Ering Sanctuary.
22. (AR) Kamle. HQ: Raga A young district, it was created in 2017 after a long-pending demand from the Nyishi community. Unsurprisingly, the name comes the river Kamle.
23. (AR) Kra Daadi. HQ: Palin A crescent-shaped district, Kra Daadi came into being in 2015. Palin, its most important town, is a hill station and home to the well-regarded Holy Rosay Catholic Church.
24. (AR) Kurung Kumey. HQ: Koloriang
Kurung and Kumey are named after rivers too! But this time, they are apparently twin streams. Also mountainous and populated by the Nyishis.
25. (AR) Lepa Rada. HQ: Basar
This district was carved out of Lower Siang only in 2018. Home to the warrior Galo tribe (A nice introduction: - including the importance of the Mithun animal to them)
26. (AR) Lohit. HQ: Tezu

33. (AR) Papum Pare. HQ: Yupia

The political centre of Arunachal Pradesh and its most populous district. The state's capital Itanagar is here (curiously, it isn't the HQ of the district), as is Naharlagun, the big railway station here.
(33. contd.)
No prizes for guessing that Papum and Pare are names of rivers in the region. Itanagar gets its name from the Ita fort, so called because it was made of bricks. Buddhism, mountains, wildlife are associated with this district.
34. (AR) Shi Yomi. HQ: Tato
Another of Arunachal's districts that came into being in 2018. Borders China and is home to mountains and valleys. The frontier Mechuka is a growing tourist attraction. The place has a 400-year old Buddhist monastery.

37. (AR) Tirap. HQ: Khonsa

And that brings us to the end of this 25 district trip through Arunachal. For a superficial browser like me, online information about many districts (esp. the new ones), is quite sparse, with even official pages being quite limited. There's a lot to learn and document, clearly.

inwards to Assam (finally, a state I've been to!). Thirty-three districts make up this heart of N-E India.
