shaheed is the translation of martyr in english to punjabi. shaheed is given to the name of martyrs in sikh history e.g shaheed baba ajit singh ji, shaheed baba jujhar singh ji, shaheed baba zorawar singh ji, baba fateh singh ji etc. in sikh history using the word shaheed is commonly used for sacrifice for a good cause similar to martyr for example the 9th guru, guru tahegbahadur ji gave his head for the kashmiri pundits after the islam rulers forced the pundits to convert to islam. so sikhs often notice this and call him shaheed too. shaheed can also be shaheedi in correlation to shaheedi gurpurab (gurpurab is like anniversary but more honoured.)
