Final answer:
The Indian states of Assam, Gujarat, Goa, and Sikkim received statehood in chronological order starting with Assam (1950), followed by Gujarat (1960), then Goa (1987), and finally Sikkim (1975).
Step-by-step explanation:
The states in question are part of the modern-day country of India and the dates they received statehood are as follows:
- Gujarat - Established on May 1, 1960, when the Bombay State was divided into Gujarat and Maharashtra.
- Assam - It was constituted as a state in the Republic of India on January 26, 1950 when the Constitution of India came into effect.
- Goa - Annexed by India in 1961, it was given statehood on May 30, 1987.
- Sikkim - Became an Indian state on May 16, 1975, after the Sikkim Referendum.
Therefore, the chronological order in which these states received statehood, from the earliest, is Assam, Gujarat, Goa, and then Sikkim.
