In the meaning 'als Ursache sehen' (to see as the cause), the fixed structure 'etwas auf etwas zurückführen' (to attribute something to something) is always used. The preposition 'auf' introduces the reason or cause and requires the accusative.

This meaning describes physical movement. In the sentence, there is usually an accusative object (who or what is being brought back?) and often an indication of place (to where?). Unlike the other meaning, the preposition 'auf' is absent here.

to cause
„Verursachen“ presents a cause as an actual causal relationship. „Zurückführen“, by contrast, describes recognizing something as the cause or justifiably attributing it to that cause; this attribution can therefore be an assessment. Use „verursachen“ for the cause itself and „zurückführen“ for explaining its cause.
