Pyin Oo Lwin: History
=== Early history and founding ===
The area was originally home to a small Shan village of about two dozen households situated on the Lashio–Mandalay trail between Nawnghkio and Mandalay.
Following the British annexation of Upper Burma in 1885, a military outpost was established at the site. In 1897, a permanent military post was founded, and the town subsequently developed into a hill station and the summer capital of British Burma owing to its cooler climate. During the hot season (March–May), the civil, commercial, and military establishments would relocate from Rangoon to Maymyo to escape the lowland heat and humidity.
The British named the settlement Maymyo—literally "May's Town" in Burmese—after Colonel May, a veteran of the Indian Rebellion of 1857 and commander of the Bengal Regiment temporarily stationed there in 1887.
The construction of the Mandalay–Lashio Railway in the late 1890s and early 1900s transformed Pyin Oo Lwin from a remote military post into an accessible hill resort. The line, built to 1,000 millimetres (3.3 ft) metre gauge, passes through the town and continues over the spectacular Gokteik Viaduct—completed in 1901 and at the time the longest railway trestle in the world—on its way to Lashio in the Shan Hills.
During the colonial period, Maymyo became one of the most important European settlements in Burma. The town was laid out with a circular road, extensive gardens, a golf course, and numerous bungalows and public buildings in the English style. The Candacraig Hotel, originally built in 1904 as a guest house for the Bombay Burmah Trading Corporation, became the social centre of the European community.
During British rule and through the 1970s, Maymyo had a large Anglo-Burmese population, which steadily declined over subsequent decades. During the Japanese occupation (1942–1945), many Anglo-Burmese concentrated in and around Maymyo were incarcerated by the Japanese, who feared their loyalty to the British.
After independence in 1948, the military government renamed the town Pyin U Lwin, a word-for-word Burmese transcription of the Shan name. However, the colonial name "Maymyo" remains in widespread colloquial use.
Today, Pyin Oo Lwin retains one of the country's larger Anglo-Burmese communities, alongside significant Indian, Gurkha, and Chinese populations.
The area is also the site of the decisive Battle of Maymyo, in which the Burmese royal army under Maha Thiha Thura defeated the Chinese during the third invasion of the Sino-Burmese War (1765–1769).
Following the February 2021 military coup, the Pyin Oo Lwin area has been affected by the ongoing Myanmar civil war. The town's large military presence—including the Defence Services Academy—has made it a strategic location. Armed clashes between the State Administration Council forces and People's Defence Force units have occurred in surrounding areas, significantly impacting the local tourism industry.
