Sri Lanka experienced decline in large-scale irrigation as the Polonnaruwa system fell into disrepair, with highland and coastal polities relying more on rainfall-fed fields.

Long-Term Significance
By 1395, Maritime South Asia was divided between Bahmani and Vijayanagara, with Sri Lanka fragmented, Maldives firmly Islamic, and the Lakshadweep–Maldives–Chagos arc firmly embedded in Indian Ocean currency and spice networks.
The Tughlaq Dynasty under Muhammad bin Tughluq holds power during the famine centered on Delhi in 1335–42.
The sultanate offers no relief to the starving residents of Delhi during this famine.
Tensions between the Muslims forced by Delhi to emigrate to the overwhelmingly Hindu province of Daulatabad had become open revolt in 1346.
After the Sultan, Muhammad Tughlaq, left Daulatabad, Maharashtra, the city had been conquered by Zafar Khan.
Independence from Delhi was immediately declared and Khan had established a sultanate of his own.
A Turkish or Afghan officer of unknown descent, Zafar Khan, whose name is Hasan Gangu, had earlier participated in a mutiny of troops in Gujarat.
When he establishes the Bahmani dynasty as Alaud-Din Bahman Shah, he probably does not feel too safe in Daulatabad, so he shifts his capital a ear later to Gulbarga (Karnataka), located in a fertile basin.
His dynasty that will rule he Deccan for nearly two centuries.
Delhi dispatches an army the following year, but troubles closer to home forces the sultanate to recall it before it is able to depose Alaud-Din, who will have to fight various remnants of Muhammad Tughlaq’s troops, as well as the Hindu rulers of Orissa and Warangal, who had also expanded their spheres of influence as soon as Muhammad had left the Deccan.
The sultanate, under its second Tughluq emperor, Muhammad, has reached its greatest extent yet, its territory stretching from Bengal to Panjab and from the Himalayas almost to the subcontinent’s southern tip.
Muhammad bin Tughluq is an able general but geography and the machinations of ambitious local rulers hinder his effective administration of an empire of this size.
Shortly after Muhammad’s death in 1351, the Sultanate shrinks to the boundaries of Sultan 'Ala'-ud-Din Khalji’s reign at the turn-of-the-century.
India’s Delhi Sultanate, beset by the eruption of numerous rebellions, devastating famine, and the ravages of bubonic plague, is unable to field its depleted armies effectively.
The Shia Muslim kingdom of Bahmani, founded in 1346, passes its first dozen years of existence primarily in consolidating its control over the western Deccan region south nearly to the Kristna, or Krishna, River, bringing it into conflict with the independent Hindu kingdom of Vijayanagar established ten years earlier.
Conflicts begin in 1350 over possession of the extremely rich and anciently contested land lying between the Tungabhadra River (Bahmani’s southern border) and the Kristna River (Vijayanagar’s northern border).
Warfare between Vijayanagar and Bahmani continues under Bahmani’s second ruler, Muhammad Shah.
Despite Muhammad Shah’s novel employment of artillery in two wars, he gains little ground in the hotly contested border area between the Kristna and Tungabhadra Rivers.
The Bahmani defeat Vijayanagar in 1365 and again in 1367, inflicting a general massacre upon their Hindu enemies to the south.
Bahmani’s ruler, Muhammad Shah I, dies in 1377.
Under his successor, Bahmani narrowly fails in its attack against the capital city of the Vijayanagar kingdom.
The assassination of the new Bahmani sultan in 1378 permits a recovering Vijayanagar to seize Goa and other west coast ports.
