Republican Arms.
During the Spanish occupation, the provinces of the Netherlands (which then included present Belgium) formed a parliament, the Staten-Generaal. A total of 17 provinces was represented. As many of the provinces had a lion in their arms, the symbol of the Staten-Generaal became a lion. A sword was added as a symbol of power and 17 arrows as a symbol of unity.

In 1579 the northern provinces united in the Union of Utrecht and formed their own Republic of the Seven United Netherlands. At the same time a similar union was formed in the South, basically dividing the Netherlands and Belgium. The Republic, which became officially independent in 1648, but was practically independent since 1579, took the arms of the 17 provinces, but changed the number of arrows to 7. As colours, the colours of Holland, the most important of the newly united provinces, were taken. The arms of Holland are or, a lion rampant gules, tongue and nails azure. These arms, sometimes with modifications, were used until the French occupation in 1795.
