Sufi master and poet Hacı Bayram Veli established the Bayramiyya (Bayramiyye) order in Ankara, creating a major Ottoman-era Anatolian Sufi network whose lodges later spread into Istanbul and the Balkans.
Hacı Bayram Veli (founder of the Bayramiyya) died in Ankara, after which the Bayramiyya continued through successors and branches that helped shape Ottoman popular religious life into the 16th century.
During the reign of Bayezid II (1481–1512), the Khalwati (Halveti) order reached a peak of influence in Ottoman Turkey, benefiting from courtly participation and patronage that strengthened its urban lodge network.
A major Istanbul religious complex associated with the later Koca Mustafa Paşa Mosque was converted for Ottoman Muslim use in the late 15th century and became a crucial Halveti/Khalwati center, illustrating how Sufi lodges were embedded in the capital’s urban fabric.
In the 16th century, the Bektashi order took on a more definitive institutional form under Balım Sultan, who is credited with structuring and systematizing its hierarchy and practices—an important step in its Ottoman-period expansion, especially into the Balkans.
The Bektashi order became closely identified with the Janissary corps, a relationship that increased the order’s visibility and influence within Ottoman military and urban religious life (even as its exact origins were shaped by tradition and later institutionalization).
A prominent Halveti sub-order, the Gülşeniyye, developed major Ottoman-era presence in Egypt; the Cairo lodge and burial complex of its founder İbrahim Gülşenî was built in the early 16th century, reflecting Ottoman-linked Sufi networks extending beyond Anatolia.
Sünbül Sinan Efendi (1452–1529) emerged as a leading figure at the Koca Mustafa Paşa tekke complex and is associated with the Sunbuliyye, a derivative of the Khalwatiyya—showing the proliferation of sub-orders within Ottoman Sufism.
Aziz Mahmud Hüdâyî—later a major Ottoman preacher, poet, and founder of the Celvetiyye (Jelveti) order—was born in the mid-16th century; his career illustrates the close ties between Sufi authority, preaching, and Ottoman urban society.
The Bayrami-linked Sufi shaykh Üftâde oversaw the completion of his Bursa dergâh/mosque complex in 1577, exemplifying how endowments and built environments supported popular religious networks in Ottoman cities.
Üftâde died in 1580 in Bursa. His disciples—most notably Aziz Mahmud Hüdâyî—carried forward connected Bayrami/Halveti currents, highlighting interlinked chains of teaching across Ottoman Sufi milieus.
Between 1593 and 1598, Aziz Mahmud Hüdâyî gained public stature through sermons at Istanbul’s Fatih Mosque, demonstrating how Sufi figures could shape mass piety through elite urban pulpits as well as lodge-based teaching.
Aziz Mahmud Hüdâyî founded the Celvetiyye (Jelveti) order, a Sufi path that remained primarily within Ottoman Anatolia (with some Balkan lodges) and became influential through preaching, devotional writing, and lodge activity.
Aziz Mahmud Hüdâyî died in Üsküdar (Istanbul) in 1628 and was buried there; his tomb and associated complex became a continuing site of devotion, underscoring the long afterlife of Ottoman Sufi saints in popular religion.
