The flag of the Czech Republic is a national emblem consisting of two equal horizontal bands—white above red—with a blue isosceles triangle issuing from the hoist. It is usually described in Czech as státní vlajka České republiky and appears on official sites such as the government information pages. The combination of white, red and blue places it among flags using Pan‑Slavic colors.

Design and characteristics

Visually the flag combines simple geometric elements. The upper stripe is white and the lower stripe is red; both are horizontal bands and of equal height. From the hoist side extends a blue isosceles triangle whose base lies on the hoist. The white and red reflect older Bohemian heraldic colors while the blue triangle provides contrast and a distinct silhouette that separates this flag from similar two‑band flags.

  • Horizontal bands: described in some sources as two equal bands of white and red.
  • Colors: white (white), red (red) and blue (blue), commonly associated with Slavic symbolism.
  • Triangle: a blue isosceles triangle based on the hoist (triangle element).

History and development

The current flag traces its origin to the early 20th century when Czechoslovakia adopted a national banner that combined Bohemian colors with a blue field to represent the broader new state. After the peaceful split of Czechoslovakia in 1993 the Czech Republic retained that flag as its national standard. Its continuity reflects historical links to earlier Bohemian symbols and to the period of Czechoslovak statehood.

Uses, protocol and contexts

The flag is displayed on government buildings, during official ceremonies, at diplomatic missions, and on certain public holidays and commemorations. Protocol typically covers proper hoisting, respectful display and procedures for half‑masting in times of national mourning. It also appears on documents, medals and other official insignia as a recognizable national symbol.

Comparisons and notable facts

While its colors are shared with other Slavic flags, the blue triangle gives the Czech flag a distinctive form compared with the plain white‑over‑red flag of neighboring Poland. The retention of the Czechoslovak design after 1993 makes it one of the modern European flags whose form predates the present state.
