01 July - Zip Code Day is observed

A ZIP Code is a postal code used by the United States Postal Service (USPS). Introduced in 1963, the basic format consisted of five digits. In 1983, an extended ZIP+4 code was introduced; it included the five digits of the ZIP Code, followed by a hyphen and four digits that designated a more specific location.

The term ZIP is an acronym for Zone Improvement Plan; it was chosen to suggest that the mail travels more efficiently and quickly[2] (zipping along) when senders use the code in the postal address. The term ZIP Code was originally registered as a service mark by the USPS, but its registration expired in 1997.

The transfer of sovereignty over Hong Kong,commonly known as the handover of Hong Kong (or simply the Handover, also the Return in mainland China), occurred at midnight at the start of 1 July 1997, when the United Kingdom ended administration for the colony of Hong Kong and returned control of the territory to China. Hong Kong became a special administrative region and continues to maintain governing and economic systems separate from those of mainland China.

This event ended 156 years of British colonial rule in Hong Kong. The territory was Britain's last substantial overseas possession. With a population of about 6.5 million in 1997, Hong Kong constituted 97% of the total population of all British Dependent Territories at the time.

30 June - The Santhal rebellion 1855

The Santhal rebellion (sometimes referred to as the Sonthal rebellion), commonly known as Santhal Hool, was a rebellion in present-day Jharkhand, in eastern India against both the British colonial authority and zamindari system by the Santhal people. It started on June 30, 1855 and on November 10, 1855 martial law was proclaimed which lasted until January 3, 1856 when martial law was suspended and the movement was brutally ended by troops loyal to the British. The rebellion was led by the four Murmu Brothers - Sidhu, Kanhu, Chand and Bhairav.

The uprising of the Santhals began as a reaction to end despotic British revenue system, usury practices, and the zamindari system in India; in the tribal belt of what was then known as the Bengal Presidency. It was a revolt against the oppression of the colonial rule propagated through a distorted revenue system, enforced by the local zamindars, the police and the courts of the legal system set up by the British.

The Santhals lived in and depended on forests. In 1832, the British demarcated the Damin-i-koh region in present day Jharkhand and invited Santhals to settle in the region. Due to promises of land and economic amenities a large numbers of Santhals came to settle from Cuttack, Dhalbhum, Manbhum, Hazaribagh, Midnapore etc. Soon, mahajans and zamindars as tax-collecting intermediaries deployed by British dominated the economy. Many Santals became victims of corrupt money lending practices. They were lent money at exorbitant rates when they never repay then their lands were forcibly taken, they were forced into bonded labour. This sparked the Santal rebellion by Sidhu and Kanhu Murmu, two brothers who led the Santals against the Britishers but were defeated.
