Coat of arms of Libya
Since the collapse of the Gaddafi regime in the Libyan civil war, Libya currently does not have an official coat of arms. The Constitutional Declaration issued by the National Transitional Council on August 2011 defines the flag of Libya, but does not make any provisions for a coat of arms.
One emblem that is used for official purposes is a seal that has been adopted by the Libyan legislature, the General National Congress. This seal depicts a crescent moon and star surrounded by the name of the congress written in Arabic and English. It is used to certify documents issued and laws passed by the congress. 
Other emblems that are used for governmental purposes are the seals of the interim Prime Minister's office and the departments of the interim government. These seals usually consist of an outline map of Libya in the design of the Libyan flag surrounded by the name of the office or department written in Arabic. 
Kingdom of Libya (1951–1969)
The emblem of the Kingdom of Libya, known as the "Crown of Libya", was used from 1952-1969.
The constitution of the Kingdom of Libya of 1952 in article 7 describes the flag, but not the emblem. No official description is available at present (due to the restrictions placed on government archives since the military coup of 1969), and the design is reconstructed from many variants in shape and color schemes. The design as represented in official government sources of 1952-1969, which describes the emblem, is as follows:
- Upper crown adorned with a white Crescent and five-pointed star at its summit, at which five visible side frames originating from a ring at the base converge. The star studded base and frame contain a velvet black head cover like object.
- The Upper crown is supported at its base by two ornate plantar designs; in the form of three intertwined C and S scroll shapes.
- Two massive “Shoulder” frames contain the body of the crown from the right and left [...]. Each side is a complex formation of intertwined branches in the shape of an S Curve, which is essentially two back-to-back C scrolls; the larger one of which terminates in a large beautiful spiral at the top. [...]
- The background color of the large interior below the upper crown can be white or transparent, although this is not evident in the picture of the Libyan pound. The background color of the center region surrounding the large white crescent and star is black as in the center stripe of the Libyan flag.
- A white ring with thin black borders, surrounds the center large white crescent and star.
- Nine five-pointed white stars surround the center ring.
- Large white crescent.
- Five pointed star located well above the perimeter of the crescent. This differs from the flag, which places the star at the extremities of the crescent.
- A lower crown, seated above the ring containing the central crescent and star. Its design is identical to the upper crown, except for being smaller in size.
- Plantar/ floral ornamentation similar to #2 above, providing variation and connectivity to the base.
- At the base, an ornate design that resembles a document scroll with a ring tie at its center. It is noted that the color scheme of the crown is most likely white for the stars and crescents, black and white (or transparent) for spaces, and gold for the crowns and frames. [...]
The upward-pointing white crescent and star on black background is taken from the traditional banner of the Senussi dynasty.
Libya under Gaddafi (1969-2011)
In 1970, Libya adopted as its coat of arms the Eagle of Saladin, which had become a symbol of Arab nationalism following its prominence in the Egyptian Revolution of 1952, after which it was used in the coat of arms of Egypt, the United Arab Republic, Yemen, and Iraq. In 1972, Libya's participation in the Federation of Arab Republics led both it and Egypt to abandon the Eagle of Saladin, and to adopt as their coats of arms the Hawk of Quraish, the emblem of the tribe of the Prophet Muhammad used by Syria, which became the coat of arms of the Federation. On Libya's exit from the Federation in 1977 (to become the "Great Socialist People's Libyan Arab Jamahiriya"), the Hawk of the Quraish was retained, but modified to reflect the new all green flag that Libya also adopted at that time. The hawk was also changed to face in the other direction. The phrase اتحاد الجمهوريات العربية (ittiħād al-jumhūriyyāt al-`arabiyya "Federation (literally Union) of Arab Republics") still remained written on the banner clutched in the feet of the hawk.
Libya under the National Transitional Council (2011-2012)
The National Transitional Council, supported as the legitimate administration by the United Nations since September 2011, used a seal that depicts a crescent moon and star, represented in the colors of the Libyan flag (red, black, and green), with the names of the council المجلس الوطني الانتقالي (al-majlis al-waṭanī al-intiqālī, "The Transitional National Council") and of the state ليبيا (Lībiyā, Libya) displayed in Arabic and English.
