Second Anglo Mysore War: Causes, Events, and Outcome

Ask most people about the East India Company and they picture a slow, steady takeover of India. Sign a treaty here, plant a garrison there. The Second Anglo-Mysore War doesn’t fit that picture at all. For four years, the Company got badly beaten, badly scared, and eventually had to sit down and negotiate as equals with an Indian kingdom, which was not something it did often.

Fought between 1780 and 1784, the second Anglo Mysore war 1780 pulled in the French, the Dutch, the Marathas and the Nizam of Hyderabad, and at one point it looked like Mysore might actually push the British out of southern India for good. It didn’t happen, but it came close enough to leave a mark on how both sides fought every war after this one.

What Was the Second Anglo-Mysore War

In plain terms, the second Anglo Mysore war was fought between the British East India Company and the Kingdom of Mysore, first under Hyder Ali and then, after his death partway through the war, under his son Tipu Sultan. It ran from 1780 to 1784, mostly across the Carnatic and the Malabar coast, and it was a rougher, bloodier affair than the first war between the two sides. Europe’s politics spilled straight into it too.

Britain happened to be at war with France and the Dutch Republic at the same time, and Hyder Ali, ever the strategist, used that to his advantage by pulling both powers onto his side.  A local rivalry, in other words, turned into something much bigger almost overnight.

Causes of the Second Anglo-Mysore War

Wars like this one rarely have a single trigger, and the causes of the second Anglo Mysore war are a good example of how grievances pile up quietly before they explode.

Start with trust, or the lack of it. Hyder Ali had never really forgiven the British for sitting out when the Marathas attacked Mysore after the first war, despite having promised support. That kind of broken word doesn’t get forgotten easily. Add to it the British habit of expanding wherever they could, and Hyder Ali had good reason to feel boxed in.

Then came the spark. In 1779 the British grabbed Mahe, a small French port that sat under Mysore’s protection. To Hyder Ali, this wasn’t just a land grab, it was a message that his word and his territory meant nothing to the Company. Around the same time, the British were cosying up to the Nawab of Arcot and the Nizam of Hyderabad, two rulers Mysore did not get along with, which made things feel even more like an encirclement than a coincidence.

And underneath all of it sat the French connection. Britain and France were already at odds in Europe, so when Hyder Ali reached out to the French, and to the Dutch as well, it wasn’t hard to see why. He needed muscle, and this was where he could get it. By the time fighting actually broke out, it was less a sudden outburst and more the last straw on a pile that had been building for years.

Key People Behind the War

Hyder Ali

Hyder Ali wasn’t your typical regional ruler. He built an army trained along European lines, which was rare for an Indian kingdom at the time, and he had a knack for using tactics the British simply didn’t expect. Off the battlefield he was just as invested in growing Mysore’s trade and its cultural life, so the kingdom he handed to his son wasn’t just militarily strong, it was economically solid too.

Lord Warren Hastings

As Governor-General, Warren Hastings had his hands full. He’s better remembered today for setting up the Supreme Court of Calcutta and other administrative reforms, but through this war his real job was holding a shaky campaign together while juggling multiple fronts against an opponent who kept outmanoeuvring him.

Sir Eyre Coote

Sir Eyre Coote is the man who kept the British side from falling apart entirely. He led troops through some of the war’s hardest fighting, including Porto Novo and Pollilur, and his experience mattered a lot in a war where the British were often caught off guard.

Major Battles of the Second Anglo-Mysore War

Battle of Pollilur

Pollilur, fought on September 10, 1780, is the one battle everyone remembers from this war, and for good reason. Hyder Ali and Tipu Sultan led their forces against a British column under Sir Hector Munro, and they brought something the British had never really faced before: rocket artillery. It tore through the British ranks. What followed was one of the worst defeats the East India Company had ever taken on Indian soil, with most of the force lost along with its guns and supplies.

Siege of Tellicherry

Fast forward to April 1783, and the tables had turned a little. Tipu Sultan went after Tellicherry, a British trading post on the Malabar coast, expecting an easy win. He didn’t get one. The defenders, led by Captain Thomas Bowser, held the line and forced the Mysorean army to retreat after taking heavy losses. It was a small but telling reminder that the British hadn’t been knocked out of the fight, not by a long way.

The Treaty of Mangalore

By 1784, both sides were exhausted, and neither had much appetite left for dragging the war on. That’s what led to the Treaty of Mangalore, signed on March 11, 1784, between Sir Archibald Campbell for the British and Tipu Sultan, who was now ruling Mysore after Hyder Ali’s death in 1782.

The terms were fairly simple on paper: give back what you took. The British returned Mangalore, Mysore returned forts like Chittledroog and Gooty, and prisoners went home on both sides. There was even a mutual defence clause thrown in. It all sounded like peace, but the truth is, the mistrust between the two sides never actually left the room. It just went quiet for a while.

Aftermath and Impact

The war changed more than a few lines on a map. Mysore came out of it weaker, no surprise really, since it had lost Hyder Ali, the one man who had built its strength up in the first place. The British, meanwhile, used the years after the war to quietly tighten their hold over the south, eventually pulling territories like Bangalore into their orbit.

France’s standing in India took a hit too, since its closest ally in the region had fought the British to a draw rather than a win. And for Tipu Sultan, this war was where his story as a ruler really began. He stepped up young, carried his father’s fight forward, and that stubbornness would define the rest of his life, right through to the wars still to come.

Why the Second Anglo-Mysore War Still Matters

Decades on, this war still gets talked about, and not just as a footnote. It’s the moment Tipu Sultan stopped being Hyder Ali’s son and started being his own man, one of the most stubborn opponents British rule ever faced in India.

It also proved something that gets easy to forget when you only read about British conquest: Indian kingdoms could, and did, outfight European forces when the strategy and the timing were right. That idea stuck around and shaped how later resistance to colonial rule got remembered. If you want to go deeper into this period, and how it connects to the wars that came after, BharatStories has more detailed reading on the subject.

Frequently Asked Questions

Who won the Second Anglo-Mysore War?

Nobody really won it. The war ended in a stalemate, and the Treaty of Mangalore put things back roughly where they stood before the fighting started, which is why it’s usually described as a status quo ante bellum outcome instead of a clean victory for either side.

What were the causes of the Second Anglo-Mysore War?

It came down to British expansion in the south, the seizure of the French port of Mahe, British backing for Mysore’s rivals like the Nawab of Arcot, and Hyder Ali’s alliance with the French. All of it built up over time until it spilled into open war.

The second Anglo Mysore war fought between which two sides exactly?

The British East India Company on one side, and the Kingdom of Mysore on the other, first under Hyder Ali and then his son Tipu Sultan, with France and the Dutch Republic backing Mysore.

What was the significance of the Treaty of Mangalore?

It formally ended the war in 1784 and returned captured land and prisoners on both sides. It brought a pause in the fighting, sure, but it didn’t really settle the distrust between Mysore and the British, which came back around in later conflicts.

How did the Battle of Pollilur affect the war?

It was the turning point early on. Mysore’s rocket artillery caught the British completely off guard and handed them one of their heaviest losses in India up to that point, which gave Mysore the upper hand for a good stretch of the war.

What happened to Tipu Sultan after the war?

He took over as ruler of Mysore after his father died in 1782 and kept pushing back against British influence long after the Treaty of Mangalore was signed, a stance that eventually led to more wars with the East India Company.
