How Telangana got its map: taluks, mandals and the 33 districts

A revenue officer lives inside a map: her powers, her records and her appeals all run along district, division and mandal lines. Telangana’s map is young — most of it was drawn in 2016 — but its logic is old, and the seams between old and new maps are exactly where files get lost and jurisdictions get confused. This article is the map’s biography.

The inherited map: nine districts, then ten

The districts Telangana brought into the merger of 1956 were Hyderabad State’s Telugu districts, themselves descendants of Salar Jung’s nineteenth-century zilabandi: Hyderabad, Medak, Nizamabad, Mahbubnagar, Nalgonda, Warangal, Karimnagar, Adilabad — and Khammam, carved out of Warangal in 1953. Below the district sat the taluk under a tahsildar, and below that the firka, a Revenue Inspector’s circle of villages.

The AP decades changed the district map exactly once: in 1978, Ranga Reddy district was formed from the rural surroundings of Hyderabad district (named for K.V. Ranga Reddy), leaving Hyderabad a compact urban district. Ten districts, then, from 1978 to 2016 — the “erstwhile districts” of every conversation you will have with older colleagues and older files.

The legal machinery for all of this is worth knowing: districts, divisions and mandals are not created by statute-per-district but by government notification under the Districts (Formation) Act, 1974 — draft notification, objections, final notification. That is why the map can move as fast as a government wishes.

1985–86: taluks become mandals

The first great re-scaling happened below the district. In 1985–86 the NTR government replaced the large taluks with far more numerous, far smaller mandals, each with its own revenue office under a Mandal Revenue Officer (the Tahsildar under a new name, later renamed back). Firkas survived as RI circles within mandals. The declared purpose was the same one that would drive 2016: shrink the unit until the office is within a citizen’s day-trip.

The consequences for records were permanent. Every record series older than 1986 is organised by taluk; one taluk’s territory typically became several mandals, and its record room’s contents were divided — or were not, and stayed at the old headquarters. “Which taluk was this village in before 1986?” is the first question of any legacy-record hunt.

2016: ten districts become thirty-one

On 11 October 2016 — Vijayadashami — the state brought the same logic to the district tier, splitting its 10 districts into 31 in a single coordinated notification exercise under the 1974 Act. Two more followed in February 2019 — Mulugu (out of Jayashankar Bhupalpally) and Narayanpet (out of Mahabubnagar) — bringing the number to 33, where it has stayed.

The stated rationale was administrative proximity: districts small enough for a Collector to actually know — average populations dropped from the tens of lakhs to roughly a third of that — with every new district getting a full Collectorate, police district and line-department set. The re-scaling ran down the whole ladder: revenue divisions multiplied, and 125 new mandals were created alongside the new districts (584 mandals at reorganisation), with a further 13 mandals notified later.

Naming carried the politics of memory: several districts honour movement and tribal icons — Jayashankar Bhupalpally (Prof. Jayashankar, the movement’s ideologue) and Komaram Bheem Asifabad (the Gond rebel leader) among them — and in 2021 the Warangal pair was renamed, Warangal Urban becoming Hanumakonda and Warangal Rural reverting to Warangal.

The map as of 2026

• 33 districts.
• 74 revenue divisions, each under an RDO or Sub-Collector — districts have between one and five divisions (Ranga Reddy, with five, the largest).
• ~594 revenue mandals — treat 594 as the standard citable figure (584 at reorganisation plus 13 notified later; confirm against the latest CCLA/DES handbook before publishing any official count), each under a Tahsildar.
• ~10,909 revenue villages, the unchanging atoms beneath everything.

The division deserves a word, because it is the tier a Deputy Collector inhabits. A division is a Collector-in-miniature’s charge: a cluster of mandals whose Tahsildars the RDO supervises, the first-appeal forum in record-of-rights matters under the Bhu Bharati Act, the land-acquisition unit, and the Sub-Divisional Magistrate’s jurisdiction. When divisions multiplied with the 2016 districts, appellate and magisterial geography multiplied with them.

What reorganisation did to records, jurisdictions and cadres

Records. The saving grace of every reorganisation is that the revenue record is keyed to the village and survey number, not to the district. No survey number was renumbered in 2016; the sethwar, pahani and RoR of a village are the same documents whatever district it sits in. What moved was custody and continuity: files opened in the erstwhile district’s Collectorate mostly stayed there physically, while jurisdiction over them passed to the new district — so a ceiling case from 1978 concerning a village now in Siddipet may live in the Medak record room. Legacy-record requests routinely bounce between successor offices; the officer who first establishes the village’s full lineage (firka → taluk → old mandal/division/district → new) saves weeks.

Jurisdictions. Every forum defined by territory shifted: which RDO hears the appeal, which Collector the second appeal, which magistrate the security proceeding. Cases pending on the changeover dates were transferred by notification, and boundary-adjacent villages were sometimes moved between mandals in later corrections — always verify a village’s current mandal and division from the portal rather than memory or an old file cover.

Cadres. Employees belong to local cadres organised by district and zone under Article 371D, so redrawing districts forced a re-allotment of staff to new units — and, in 2018, a Presidential-Order revision of the zonal system itself to fit the 33-district map (a new multi-zone structure for recruitment and seniority). Seniority lists, transfer counselling and recruitment rosters all now run on the new geography; disputes seeded by the re-allotment still surface in service matters.

Statistics and schemes. Any data series that crosses 2016 breaks: crop, rainfall, scheme and revenue figures were compiled for 10 districts before and 31/33 after. Comparisons across the break must be built village-up. Older G.O.s and manuals also cite erstwhile districts — mentally translate before applying them.

Misconceptions

• “District reorganisation changed land records.” It did not touch them. The record is village-keyed; reorganisation changed which offices hold and act on the records, not the records themselves.
• “33 districts was one decision.” It was 31 in October 2016 plus two in February 2019 — and mandal counts kept moving after, which is why the ~594 figure should be cited as the standard number rather than an eternal truth.
• “Mandals are old.” Younger than many serving officers: 1985–86. The taluk is the older unit, and the older records follow it.
• “The erstwhile districts are gone.” They live on as the organising unit of pre-2016 files, statistics, service seniority and everyday speech (“erstwhile Warangal”, “old Adilabad”). Fluency in both maps is a working skill, not nostalgia.

Questions you’ll actually get

“Which division and district is village X in now?” Look it up on the portal every time — post-2016 corrections moved some villages between mandals, and memory is the least reliable gazetteer in the state.

“Where is the 1982 ceiling file for a village now in a new district?” Almost certainly in the erstwhile district’s Collectorate record room. Establish the village’s old taluk and district, then address the successor office that inherited that series.

“Why does this G.O. mention only ten districts?” It predates October 2016. Its territorial references must be read against the old map and translated — the G.O. usually still applies, but to the successor units.

“How many mandals does Telangana have?” About 594 is the standard citable figure as of 2026 — 584 created at reorganisation plus 13 notified later. For anything official, confirm against the latest CCLA or DES handbook.

Field note for a probationer

On your first week in any posting, draw your own two-layer map: your current district with its divisions and mandals on top, and beneath it the erstwhile district, taluks and firkas the same territory belonged to. Pin it above your desk. Every legacy record hunt, every old G.O., and half the petitions of elderly parties speak the bottom layer’s language — and the officer who can move between the layers without calling for help owns the room.
