How did ghazis and timur thelame relate to the ottoman?

Ghazis were warrior champions of Islam who sought to expand Muslim territories, and they played a crucial role in the early expansion of the Ottoman Empire by participating in campaigns against non-Muslim states. Timur the Lame, or Tamerlane, was a Central Asian conqueror who sought to restore the Mongol Empire and viewed the Ottomans as rivals. His conquests in the late 14th century ultimately weakened the region, leading to a temporary setback for the Ottomans, who would later rise again under Osman I and his successors. Thus, while the ghazis contributed to Ottoman growth, Timur's ambitions posed significant challenges to their expansion.
