The halberd and partisan are hafted weapons highly favored by European infantries of the 1500s and 1600s for their great versatility and deadly effect. From about 1550 on, these weapons underwent significant changes as they gradually became more ornamental. The large flat surfaces of the blades lent themselves to engraving, etching, gilding, and other forms of decoration. They also provided the perfect location for the coats of arms of princely or noble families. For this reason, hafted weapons became the favored parade weapons of palace guards and splendidly outfitted special regiments of princely bodyguards. These examples, made for the German dukes of Brunswick at Schloss Blankenburg, still have their silk tassels in their original colors of blue and yellow.
