in 1852, two years after the execution of the báb, a fringe element in the bábí community made an unskilled plot against the shah, nasser-al-din shah, in retaliation for the báb's execution. while baháʼu'lláh condemned the plan strongly, and renounced the movement's early anti-qajar stance, on august 15, 1852 the radicalized bábís attempted the assassination of the shah and failed. notwithstanding the assassins' claim that they were working alone, and that baháʼu'lláh had not participated in the assassination attempt, the entire bábí community was blamed, and a slaughter of several thousand bábís followed. from that time nasser al-din shah qajar always remained suspicious of the bábís and baha'is and viewed them as agitators similar to the european anarchists.
