As of 25 June 2019, India is ranked first in Tests, second in ODIs and fifth in T20Is by the ICC. Virat Kohli is the current captain of the team across all formats, while the head coach is Ravi Shastri. The Indian cricket team has rivalries with other Test-playing nations, most notably with Pakistan, the political arch-rival of India. However, in recent times, rivalries with nations like Australia, South Africa and England have also gained prominence.
India was invited to The Imperial Cricket Council in 1926, and made their debut as a Test playing nation in England in 1932, led by CK Nayudu, who was considered as the best Indian batsman at the time. The one-off Test match between the two sides was played at Lord's in London. The team was not strong in their batting at this point and went on to lose by 158 runs. India hosted its first Test series in the year 1933. England was the visiting team that played 2 Tests in Bombay (now Mumbai) and Calcutta (now Kolkata). The visitors won the series 2-0. The Indian team continued to improve throughout the 1930s and '40s but did not achieve an international victory during this period. In the early 1940s, India didn't play any Test cricket due to the Second World War. The team's first series as an independent country was in late 1947 against Sir Donald Bradman's Invincibles (a name given to the Australia national cricket team of that time). It was also the first Test series India played which was not against England. Australia won the five-match series 4–0, with Bradman tormenting the Indian bowling in his final Australian summer. India subsequently played their first Test series at home not against England against the West Indies in 1948. West Indies won the 5-Test series 1–0.
Cricket entered a new era in 1963 when English counties introduced the limited overs variant. As it was sure to produce a result, limited overs cricket was lucrative and the number of matches increased. The first Limited Overs International was played in 1971 and the governing International Cricket Council (ICC), seeing its potential, staged the first limited overs Cricket World Cup in 1975. In the 21st century, a new limited overs form, Twenty20, made an immediate impact. On 22 June 2017, Afghanistan and Ireland became the 11th and 12th ICC full members, enabling them to play Test cricket.
The main objective of each team is to score more runs than their opponents but, in some forms of cricket, it is also necessary to dismiss all of the opposition batsmen in their final innings in order to win the match, which would otherwise be drawn. If the team batting last is all out having scored fewer runs than their opponents, they are said to have "lost by n runs" (where n is the difference between the aggregate number of runs scored by the teams). If the team that bats last scores enough runs to win, it is said to have "won by n wickets", where n is the number of wickets left to fall. For example, a team that passes its opponents' total having lost six wickets (i.e., six of their batsmen have been dismissed) have won the match "by four wickets".
