1046

Year 1046 (MXLVI) was a common year starting on Wednesday of the Julian calendar.

• Autumn – King Henry III ("the Black") travels to Italy to secure the imposition of Guido da Velate, archbishop of Milan, and other similarly loyal candidates in other sees (like Ravenna, Verona and Modena).
• Vata pagan uprising in the Kingdom of Hungary: Peter, King of Hungary ("the Venetian"), is overthrown after a 2-year reign and perhaps executed. Bishops Gerard of Csanád and Bystrík (or Bestricus) are stoned to death in Budapest.

• Bao Zheng (Lord Bao), a Chinese government officer during the reign of Emperor Renzong of Song, writes a memorial to the throne. He warns about governmental corruption – and a foreseeable bankruptcy of the Chinese iron industry – if increasingly poorer families continued to be listed on the register for iron-smelting households (while rich households avoid being listed for fear of financial calamity). Apparently the government heeds the warning, and produces more iron products by the year 1078 than China ever had before.
