Starting from Bengal in the second half of the 18th century, a series of battles for north Indian lands finally gave the British East India Company accession over the state's territories.  Ajmer and Jaipur kingdoms were also included in this northern territory, which was named the " North-Western Provinces " (of Agra). Although UP later became the fifth-largest state of India, NWPA was one of the smallest states of the British Indian empire.  Its capital shifted twice between Agra and Allahabad. 
Cultivation is intensive.  The valley areas have fertile and rich soil. There is intensive cultivation on terraced hill slopes, but irrigation facilities are deficient.  The Siwalik Range which forms the southern foothills of the Himalayas , slopes down into a boulder bed called 'bhadhar'.  The transitional belt running along the entire length of the state is called the terai and bhabhar area. It has rich forests, cutting across it are innumerable streams which swell into raging torrents during the monsoon. 
Tropical dry deciduous forests are found in all parts of the plains. Since much sunlight reaches the ground, shrubs and grasses are also abundant.  Large tracts of these forests have been cleared for cultivation. Tropical thorny forests, consisting of widely scattered thorny trees, mainly babool are mostly found in the southwestern parts of the state.  These forests are confined to areas which have low annual rainfall (50–70 cm), a mean annual temperature of 25–27 °C and low humidity.
