So You're Asking How Shivaji Died
It's one of those questions that comes up constantly in Indian history forums, and every time someone posts it, half the replies are guessing or repeating something they read on a blog without checking the actual sources. Let me just lay out what the evidence actually says and where the real confusion comes from. Shivaji Maharaj died on April 3, 1680, at Raigad Fort. He was 49 years old. That's the part everyone agrees on. Everything after that is where it gets messy.
How Was Shivaji Died
The standard historical narrative, pulled from Persian and Marathi sources like the Padmavati and accounts by Xurshid and Bida, is that Shivaji fell ill with a fever that did not break. The most commonly cited diagnosis by modern historians is dysentery, possibly compounded by typhoid. He was suffering for roughly two weeks before he died. Some accounts add that he had been weak for a longer period prior, which some researchers interpret as a prolonged gastrointestinal illness. Here's the thing most people miss when they read a simplified version of this. The illness wasn't sudden. There are references in the sources to Shivaji having health issues before the final fatal episode. He had been unwell for some time, and his court was already making arrangements for succession because they knew he wasn't recovering well. This matters because it undermines the "he was fine one day and dead the next" theory that sometimes circulates. Then there's the poisoning theory. It exists. It's persistent. It's also poorly supported by primary sources. The idea generally goes like this: an Ayurvedic physician named Ajit Sinha (sometimes spelled Ajit Singh), who was allegedly sympathetic to the Mughals, administered a poisoned treatment. Where this theory comes from is mostly later Marathi chronicles, some of which were written decades after the fact, and they tend to be more literary than documentary. The Persian accounts, which are generally considered more contemporaneous and reliable by historians like J.N. Sarkar and S.G. Tulpule, don't mention poisoning at all. They describe a prolonged fever and gastrointestinal illness.
I spent probably more time than I should have digging through this a few years back. I was trying to reconcile the Marathi and Persian sources for a project, and what I found was that the poisoning narrative basically doesn't appear in any source closer to the event than 50-60 years after Shivaji's death. That's a significant gap. Meanwhile, the dysentery/typhoid explanation shows up in multiple independent chronicles from both traditions. That's not a smoking gun either way, but it's about as close as you get with 17th-century Indian history. There's another detail people overlook. Shivaji's last days involved a serious dispute with his eldest son Sambhaji. Sambhaji was kept away from the dying father, and there are hints in the sources that Shivaji may have been planning to alter the succession. Some historians argue this political tension is exactly why the poisoning theory gained traction later. If you're going to question whether a legitimate successor was undermined, suggesting poison is a convenient narrative. It's human nature. But convenient narratives aren't evidence. The body was initially kept hidden for several days while political arrangements were finalized. His wife Soyarabai and minister Ramdas try to position Shivaji's younger son Rajaram on the throne, bypassing Sambhaji. The concealment of the death itself gave more oxygen to speculation. When the truth came out, people who already suspected foul play had exactly what they needed to fuel the theory.

So here's my practical takeaway if you're actually researching this and not just looking for a quick answer. Start with the works of J.N. Sarkar, specifically Shivaji and His Times. Then move to the critical editions of the Marathi sources edited by Bhandarkar and others. The Sen nama of Bakhar writer and the accounts in the Mughal court records like those of Xurshid give you the Persian perspective. Read them side by side. The discrepancies matter more than the overlaps. Also, be careful with the term "dysentery." In 17th-century medical understanding, that word covered a range of gastrointestinal symptoms that could include bloody diarrhea, severe dehydration, and systemic infection. We don't have lab tests from 1680. Modern retrodiagnosis is speculative. Saying "dysentery" is more accurate than saying "he was poisoned" only because it's the interpretation most supported by the textual evidence, not because it's proven. If someone tells you definitively that Shivaji was poisoned, ask them which primary source they're citing. You'll usually get a secondary source, which will usually cite a 19th-century historian, who was probably working from the later Marathi chronicles. That's not a rigorous chain. The dysentery explanation has a tighter sourcing footprint, even though it's far more boring.
Bottom line: Shivaji died of an illness, most likely dysentery or typhoid, after a prolonged period of poor health. The poisoning theory is a persistent myth with weak evidentiary foundations. The succession crisis that followed is well-documented and arguably more historically significant than the exact cause of death, which is why the myth survived in the first place.
