  • The Ming dynasty government of China begins a decade-long series of issuing harsh edicts towards those who illegally mine silver, the latter known as 'miner bandits' (kuangzei), a trend begun in 1438. The government wants to cap the amount of silver circulating into the market as more grain taxes are converted into silver taxes. The government establishes community night watches known as 'watches and tithings' (baojia) who ensure that illegal mining activities are brought to a halt. However, these are desperate measures, as illegal silver mining continues to thrive as a dangerous but lucrative venture.
