When a date, border or fact in the atlas conflicts with its source, it is corrected and listed here with the date. Each entry says what changed and which source it rests on. To report an error, use the contact page. Report an error →

Two records removed: 1398 truce with Hungary, 1569 treaty with Poland No support could be found in the TDV Encyclopedia of Islam or in the other articles checked for the “Truce with Hungary (1398)” shown under Bayezid I or the “Treaty with Poland (1569)” shown under Selim II. Both records were removed from the event list and the sultan pages; their old addresses now lead to the sultan's page.
Event pages: TDV Encyclopedia of Islam instead of Wikipedia The Wikipedia-based text on 142 battle, siege and treaty pages was replaced with new text based on articles of the TDV Encyclopedia of Islam; each page names the article it relies on. Troop and casualty figures and fields such as “part of” taken from Wikipedia infoboxes were removed. Where the sources give different dates or outcomes (for example the Sinop raid, the Treaty of Hamadan, the battle of Snake Island) both are stated. The page on the battle of Sırpsındığı now notes that, according to the TDV, it is the same event as the battle of Chernomen (1371). Titles of events whose name already contains a year no longer repeat the year.
Baghdad: 1624 → 1623 The fall of Baghdad to the Safavids was shown in 1624; since the TDV article “Bağdat” dates the surrender of the citadel to 28 November 1623, the year was changed to 1623. The TDV article “Murad IV” gives the same event as 1624 from the hijri year 1033, so the record is marked “disputed date”. The city page already said 1623.
Territorial records: Tabriz, Tunis, Kars The Azerbaijan (Tabriz) region was shown as Ottoman from 1534 to 1555 under Suleiman; according to the TDV article “Tebriz” the city was taken in 1534 and evacuated almost at once, so the record was removed. The region's second gain was moved from 1590 (Treaty of Ferhad Pasha) to 1585, when Tabriz was actually taken (TDV “Murad III”). Tunis was moved from 1574 to 1569 (TDV “Tunus”; the Spanish occupation of 1573–1574 was reversed and is not subtracted). For Kars a gain in 1537 and a loss in 1565 were added, and the second gain moved from 1578 to 1576 (TDV “Kars”).
City pages: Kütahya, Afyonkarahisar, Kastamonu, Samsun Early Ottoman periods given in the TDV city articles but missing from the pages were added: Kütahya 1381 (Germiyan dowry), Afyonkarahisar 1390–1402, Kastamonu 1392–1402, Samsun 1398–1402.
Consistency check and “disputed date” mark The map, city pages, event pages and map tours are now compared with one another at every build; the two corrections above were found this way. Records for which the sources give different years (for example the conquest of Edirne) are shown on the map with a “disputed date” note.
The Ottoman Army page The opening image is now labelled as showing a 16th-century army; the earliest record of muskets among the Janissaries (1455, Novo Brdo; TDV “Yeniçeri”) was added; the founding period received an image without firearms.
Measure for losses: the actual year Gains were counted in the year they actually happened but losses in the year of the treaty; both now follow the same rule. 52 losses were moved to the year they actually happened (for example Buda 1686 instead of 1699; Transylvania, Slavonia and the Morea 1687; Belgrade 1717; Crimea 1771); the recovery of Kars was moved from 1921 to 1920.
Historian review rounds Regions were split to the scale of events (for example Bithynia, Bursa 1326, Kocaeli 1337); the counting of vassal lands was brought under a single rule (Serbia and Wallachia drop out in 1402 and return in 1413); Hatay (1939) was removed from the data because the atlas ends in 1938; the 1926 Treaty of Ankara (Mosul) was added.
How to cite the atlas
Every page of the atlas ends with a ready-made citation line for that page. General form: Atlas of the Sultans, “Page title”, page address (date last updated). In academic work we recommend also consulting the TDV Encyclopedia of Islam article or the work named in the relevant line rather than citing the atlas alone; the atlas is a compilation of these sources.
