Sylhet, Bangladesh

With a population of over 9.8 million, Sylhet is a crowded, bustling division in northeastern Bangladesh. The tea industry dominates the economy, employing over 300,000 workers, most of them women paid less than men. But behind the lush landscapes lies a persistent bureaucratic headache - the division was shuffled between Bengal and Assam provinces for decades before finally joining East Pakistan in 1947, a decision met with allegations of electoral fraud. Sylhet's tropical monsoon climate brings heavy rains nearly half the year, while the region also sits on an earthquake-prone zone. For those willing to navigate the administrative complexities and weather extremes, Sylhet offers natural beauty and a thriving, if chaotic, urban center.
