to intervene
To actively intervene in order to end or prevent a negative development, a conflict, or a crime. This is often done by authority figures such as the police or by referees.
Als die Demonstration gewalttätig wurde, musste die Polizei einschreiten.
When the demonstration became violent, the police had to intervene.
The word consists of 'ein-' (in) and 'schreiten' (to stride, to step). It figuratively describes how someone 'steps into' a situation in order to take action and restore order.
Der Schiedsrichter musste einschreiten, um das Foul zu ahnden.
The referee had to intervene to penalize the foul.
'Einschreiten' (to intervene) is a separable verb. In a main clause, the prefix 'ein-' comes at the end of the sentence. The perfect tense is formed with 'sein' because 'schreiten' expresses movement.
Bei dem Lärm schreitet die Polizei sofort ein.
Because of the noise, the police intervene immediately.
This verb is often used with authorities such as 'die Polizei' (the police), 'die Regierung' (the government), or 'die Behörden' (the authorities). One often intervenes 'gegen' something negative (e.g. violence) or 'bei' an event (e.g. a conflict).
Die internationale Gemeinschaft muss gegen diese Ungerechtigkeit einschreiten.
The international community must intervene against this injustice.
'Einschreiten' (to intervene) belongs to formal language and is mainly used in official, legal, or journalistic contexts. It describes decisive and authoritative intervention.
Die Aufsichtsbehörde drohte damit, bei weiteren Verstößen einzuschreiten.
The supervisory authority threatened to intervene in the event of further violations.
active / employed
'tätig werden' and 'einschreiten' both mean that someone is no longer just watching, but takes action. 'Tätig werden' is more general and can refer to many kinds of action, for example reviewing a complaint or organizing help. 'Einschreiten' is used especially when a negative situation is supposed to be stopped, such as an argument, a rule violation, or a danger. Often, people with responsibility intervene, for example police officers, teachers, or referees. The risk of confusion lies in the fact that both describe active action. However, 'einschreiten' sounds stronger and more urgent.
