Qazvin, on the plain below the Alborz, is the Sunni frontier town against the Nizari Ismailis of Alamut and Rudbar, a day's march to the north, and the junction of the roads from Rayy to Zanjan and Tabriz and from the Jibal into Gilan.
The caliph's Diwan kept it for itself in 591/1195. After the Khwarazmian victory of 592/1196 it followed Rayy, and in 1199 Tekish made it the base of his war on the Nizaris: he took their castle of Arslan-gusha (also called Qahira) near Qazvin after a four-month siege and then attacked Alamut without taking it. On 1 January 1200 a Khwarazmian governor holds Qazvin (name not pinned), and the town's own scholars and fighters carry on their century-old war with Alamut.

Qazvin was among the towns the caliph's Diwan kept for itself in its settlement with Kokche in 591/1195 (Ibn al-Athir). In 1199 Tekish besieged the Nizari castle of Arslan-gusha near Qazvin for four months and took it, then attacked Alamut (Wikipedia, TDV), which makes Qazvin his base that year.
Overlord
Ala al-Din Tekish, Khwarazmshah
What it holds
- Qazvin and its plain
- Takestan (Siyahdahan) and the road west to Abhar
- Bu'in Zahra and the southern plain
- Kharraqan (Avaj and the upland toward Hamadan; not pinned)
- The castle of Arslan-gusha near Qazvin, taken from the Nizaris in 1199 (site not securely identified)
How it was acquired
With the Jibal in 592/1196 and again in 595/1199.
Allies and rivals
Enemy: the Nizari imam Nur al-Din Muhammad II at Alamut and his castles of Rudbar and Taleqan (cas researcher's records). Rival: the Pahlavanid mamluks, who take the Jibal after Tekish's death.
How things stand that morning
Held for Tekish (medium confidence), facing a Nizari frontier raided by both sides (belt record). The khutba presumably for al-Nasir and Tekish.
Wealth
The Qazvin plain's grain, vines and orchards watered by underground canals (qanats); tolls on the roads to Zanjan, Rayy and Gilan.
Military
A Khwarazmian garrison and the town's militia of volunteers against the Nizaris (not described in the sources read). No figures.
Threats
- Nizari raids and assassins from Alamut
- The Pahlavanid mamluks
- Tekish's death
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- 19 or 20 Ramadan 596 (3 or 4 July 1200)Tekish dies near Nasa, at Shahristana, on the road from Khwarazm into Khurasan, and his son Qutb al-Din Muhammad succeeds as Ala al-Din MuhammadDepends on: Tekish's illness (a throat abscess); natural death (khw researcher's record decides) Stopped by: play that keeps Tekish alive or keeps him from travelling
- 596-597 (from July 1200), month not pinnedOn the news of Tekish's death the townsmen and the Pahlavanid mamluks rise against the Khwarazmian garrisons in the Persian lands and massacre them (Bosworth, Iranica); the Jibal towns fall to the mamluks under KokcheDepends on: Tekish's death; Muhammad turning east against the Ghurids, who invade Khurasan in 597 Stopped by: a strong Khwarazmian army kept in the Jibal; Muhammad marching west at once
Where the sources disagree
Evidence: The 1199 siege of Arslan-gusha is in Juvaini and Ibn al-Athir as summarised by Wikipedia and TDV; Qazvin's governor is not named.
On the map: The northern edge is the raided foothill zone drawn as a belt.
