Ancient Egyptian hieroglyphs ( HY-roh-glifs) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic and alphabetic elements, with more than 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic scripts that descended from Phoenician, the majority of the world's living writing systems are descendants of Egyptian hieroglyphs—most prominently the Latin and Cyrillic scripts through Greek, and the Arabic and Brahmic scripts through Aramaic.

The use of hieroglyphic writing arose from proto-literate symbol systems in the Early Bronze Age c. the 33rd century BC (Naqada III), with the first decipherable sentence written in the Egyptian language dating to the 28th century BC (Second Dynasty). Ancient Egyptian hieroglyphs developed into a mature writing system used for monumental inscription in the classical language of the Middle Kingdom period; during this period, the system used about 900 distinct signs. The use of this writing system continued through the New Kingdom and Late Period, and on into the Persian and Ptolemaic periods. Late survivals of hieroglyphic use are found well into the Roman period, extending into the 4th century AD.

During the 5th century, the permanent closing of pagan temples across Roman Egypt ultimately resulted in the ability to read and write hieroglyphs being forgotten.

Jean-François Champollion (French: [ʒɑ̃ fʁɑ̃swa ʃɑ̃pɔljɔ̃]), also known as Champollion le jeune ('the Younger'; 23 December 1790 – 4 March 1832), was a French philologist and orientalist, known primarily as the decipherer of Egyptian hieroglyphs and a founding figure in the field of Egyptology. Partially raised by his brother, the scholar Jacques Joseph Champollion-Figeac, Champollion was a child prodigy in philology, giving his first public paper on the decipherment of Demotic in his late teens. As a young man he was renowned in scientific circles, and read Coptic, Ancient Greek, Latin, Hebrew and Arabic.

During the early 19th century, French culture experienced a period of 'Egyptomania', brought on by Napoleon's discoveries in Egypt during his campaign there (1798–1801), which also brought to light the trilingual Rosetta Stone. Scholars debated the age of Egyptian civilization and the function and nature of the hieroglyphic script, which language if any it recorded, and the degree to which the signs were phonetic (representing speech sounds) or ideographic (recording semantic concepts directly). Many thought that the script was used only for sacred and ritual functions, and that as such it was unlikely to be decipherable since it was tied to esoteric and philosophical ideas, and did not record historical information. The significance of Champollion's decipherment was that he showed these assumptions to be wrong, and made it possible to begin to retrieve many kinds of information recorded by the ancient Egyptians.

Champollion lived in a period of political turmoil in France, which continuously threatened to disrupt his research in various ways. During the Napoleonic Wars, he was able to avoid conscription, but his Napoleonic allegiances meant that he was considered suspect by the subsequent Royalist regime. His own actions, sometimes brash and reckless, did not help his case.
