Commercial cultivation of tea in the district began in 1856, and induced a number of British planters to settle there. Darjeeling became the formal summer capital of the Bengal Presidency after 1864. Scottish missionaries undertook the construction of schools and welfare centres for the British residents, laying the foundation for Darjeeling's notability as a centre of education. The opening of the Darjeeling Himalayan Railway in 1881 further hastened the development of the region. In 1899, Darjeeling was rocked by major landslides that caused severe damage to the town and the native population.
