Stavros Stylianidis finished primary school in Gialousa and settled in Nicosia with his mother and sister. His father had died when he was an infant. He threw himself into biowrestling from a very young age and was very risky. He was an amateur with gunpowder and weapons. With the beginning of the struggle he joined an executive team in Nicosia and devoted himself to the manufacture of all kinds of explosive objects. The bomb placed on the bed of English Governor Harding on March 20, 1956 was of his own invention and construction, constructed in such a way as to be applied to the abdomen of the fighter who carried it under a corset. He was wanted very early and was in hiding, continuing to plot the execution of the English governor Harding and the English commander of Nicosia Clemens.

In May 1956 he had under his responsibility the villages of Lythrodontas, Mathiatis, Agia Varvara, Alhambra, Nissou, Pera Chorio, Dali, Potamia, Lymbia, Latsia and Geri in the Orini sector. During the Anglo-French offensive against Suez, when French troops were stationed near Pyroi, Stylianides’ group under the same leader managed to take a number of weapons from French hoplites, including a large anti-tank gun with 60 rounds, which hid for a long time. But later it was discovered by the English near Lythrodonta.

After the death of Afxentiou, with the annexation to the Orini sector and the villages of the Machira region, the sector was divided into sub-sectors and Stavros Stylianidis took over as sub-sector head the area of the villages of Kliros-Malountas-Deuteras and as the head of the rebel groups of the Orini sector.
