1572 — Siege of Haarlem

The siege of Haarlem was an episode of the Eighty Years' War. From 11 December 1572 to 13 July 1573 an army of Philip II of Spain laid bloody siege to the city of Haarlem in the Netherlands, whose loyalties had begun wavering during the previous summer. After the naval battle of Haarlemmermeer and the defeat of a land relief force, the starving city surrendered and the garrison was massacred. The resistance nonetheless was taken as an heroic example by the Orangists at the sieges of Alkmaar and Leiden.

2015 — 2015–2016 New Zealand flag referendums

Two referendums were held by the New Zealand Government in November/December 2015 and March 2016 to determine the nation's flag. In the first referendum, voters chose their favourite alternative flag design. The winning design then advanced to the second referendum, where it went up against the existing flag of New Zealand. The voting resulted in the retention of the existing flag. Shortly after the referendum announcement, party leaders reviewed draft legislation and selected candidates for a Flag Consideration Panel. The purpose of this group was to publicise the process, seek flag submissions and suggestions from the public, and decide on a final shortlist of options. Open consultation and design solicitation garnered 10,292 design suggestions from the public, later reduced to a longlist of 40 designs and then a shortlist of four designs to contend in the first referendum. Following a petition, the shortlist was later expanded to include a fifth design, the Red Peak. The first referendum took place between 20 November and 11 December 2015 and asked, "If the New Zealand flag changes, which flag would you prefer?"
